How to make neodymium magnets

Where to get neodymium magnets for free: list of equipment

Where can I get neodymium magnets for free?

Neodymium magnets have a powerful magnetic field, so they can be used for a wide variety of purposes. These magnets are especially in demand among craftsmen who assemble wind generators, stop meters and find other, very effective uses for neodymium magnets.

The only thing that stops such people is the price, because the cost of neodymium magnets varies from several hundred rubles to several tens of thousands. Therefore, many of them are wondering where to get neodymium magnets for free, and from what equipment and equipment they can be removed.

This article from the construction magazine samastroyka.ru will talk about where you can find neodymium magnets, and in which equipment there are the most of them.

Where to get free neodymium magnets

A considerable amount of neodymium magnets are found in old PC hard drives. Therefore, if you have an unnecessary computer hard drive at home, do not rush to throw it away. These suspensions have neodymium magnets in hard drives.

You can also find them in furniture latches. In terms of power, such magnets cannot compete with neodymium magnets from hard drives, but, nevertheless, they will definitely be useful for making homemade products somewhere.

In addition, neodymium magnets can be obtained from the following list of equipment, devices, and tools:

1. From mobile phones, players (cameras, headphones and other places);
2. Unnecessary old hard drives from a computer;
3. From disk drives and stepper motors, headphones and more;
4. From broken scanners and printers;
5. From some tools and motors.

It should be understood that in many of the above products you will not be able to find powerful neodymium magnets, for example those used to stop the meter.

Therefore, in some cases, you need to look for them in other places.

More powerful neodymium magnets are found in oil filters, magnetic separators and some other products. In this case, you should carefully disassemble and remove such a magnet, since due to heating, it can easily ignite.

Neodymium magnets from speakers

You can also remove neodymium magnets from amplification speakers, as well as other similar equipment. Recently, manufacturers of various equipment are increasingly resorting to the use of neodymium magnets.

You can also find them in some parts for cars, as well as in children's toys (usually motors).

In general, there are a lot of equipment and things from which you can get free neodymium magnets. The main thing is to take a closer look at how this or that product is designed, and whether a magnetic field is needed for its operation. If yes, then perhaps it is in it that there is a neodymium magnet.

A generator that runs on neodymium magnets. How to make it yourself

There is no such thing as free electricity, but there are many ways to make it cheaper. For example, using alternative energy sources.

They may not cover all the needs of a particular home or office, but with their work they can easily compensate for the lion’s share of the electricity consumed. Neodymium magnets are one of the popular bases for such generators.

Such a source is available for DIY assembly. In this article you will learn how to do this, using proven schemes, recommendations from experts and videos.

Generator with neodymium magnets: principle and operating diagram

Neodymium magnets are elements that allow the construction of alternative energy sources. It doesn’t matter what they are: wind, water or mechanical. We are not talking about mythological perpetual motion machines, but about completely real devices with high efficiency. In everyday life, at a minimum, they will help you charge your gadgets or car battery.

Attention! All statements about “really free” or “free” energy and perpetual motion machines based on neodymium magnets are lies that contradict the laws of physics. Any engine requires energy to operate. The task of generators based on these elements is to reduce its external consumption, while maximizing productivity.

In such devices, an ordinary pendulum is taken as the basis, and gravity will provide low-potential energy. The scheme of work is as follows:

1. At the top, the pendulum swings freely on a pair of bearings.
2. At the bottom of the pendulum arm there is an arc-shaped section with a pair of powerful neodymium magnets.
3. On a fixed support at the upper points of the pendulum’s oscillation, two electromagnets are installed, comparable in power to neodymium magnets. As the pendulum approaches, they will briefly turn on and push it away.
4. Less powerful neodymium magnets are located along the swinging arc. They are assigned the function of a rotor.
5. On a fixed platform in the lower segment of the pendulum circumference there are stator coils without a core (6-12 pieces, depending on the size of the device). Their function is to reduce inhibition.
6. Above the arc, you can place another one, smaller in the number of magnets, in size and power.
7. The electromagnets should be powered from a low-power battery of electric capacitors.
8. To convert energy into alternating current, you need to install an inverter.

Pros and cons of the design

Experts believe that to provide electricity to a country house, a pendulum with an axis 6 m long is sufficient. In this case, the electromagnets will push the neodymium magnets on the pendulum with a force of more than 100 kg. The advantages of such a device are that it does not depend on the wind or sun. In addition, such a generator does not require expensive batteries like other alternative energy generators.

However, when using it, problems cannot be ruled out:

1. At the moment the pendulum moves in the opposite direction, the polarity of the magnets may change. It is solved by including thyristors and diodes in the circuit.
2. When the pendulum hangs at the top point, a ripple effect may occur in the network. It is solved like this:

• a capacitor is installed that collects energy for a short time, preventing surges;
• a battery is installed that will collect energy for a long time;

Generator with neodymium magnets

• another generating pendulum is being constructed, which will work asynchronously with the first (when one is at the top point of the circle, the second is at the bottom).

Attention! This project cannot be implemented with ferrite magnets due to their technical characteristics.

Do-it-yourself wind generator with neodymium magnets: installation of the base

The basis for such installations is a car hub plus brake discs. The advantage is that it is easy to get (including buying used) and does not need to be thoroughly altered or supplemented:

• disassemble;
• clean off rust (for example, with a steel brush mounted on a drill);
• lubricate the parts;
• collect;
• paint the body and use it.

Neodymium magnets will be attached directly to the hub. You will need about 20 of them: approximate height 8 mm, diameter 25 mm. It is very important to position the magnets correctly, evenly and accurately - in a circle, with alternating poles. It is better to attach them with glue, which should first be tested for strength.

Advice. Traditional designers recommend first drawing out the hub or laying out the magnets on a paper model to place them at an equal distance from each other.

After all the magnets are glued, fill the surface of the disk with epoxy resin. Wind the bead along the contour. Material and method may vary:

• rough cardboard;
• flexible plastic;
• plasticine;
• thin strip of veneer.

A three-phase model is best suited for this generator. It is difficult to assemble, but has tangible advantages:

• does not produce vibration, which is the scourge of wind generators;
• silent;
• provides a constant current supply;
• generates stable power (phases compensate each other).

Wind generator assembly and installation

After completing the assembly of the rotor, you should prepare parts for the stationary part of the structure - the stator. It consists of coils of copper wire. Its cross-section should be large in diameter to reduce resistance. As a rule, winding of such coils is carried out by eye. To charge a battery at 12V at 120-150 rpm, you need about one and a half thousand turns (total for all coils). The wire is wound on ready-made parts of the future structure or homemade mock-ups.

Stators can be either round or rectangular. It all depends on the parameters of the magnets. If the shape is rectangular, it is better to have the magnetic field along the larger side. The thickness of the fixed elements must also correspond to the height of the magnets. In this case, you will get the greatest efficiency of the device.

The generator is assembled - you can begin installing the mast and assembling the propeller. For a tower, the main thing is that the device at the top has access to free air flow. If it is installed among buildings, the height should be at least 1 m higher than the level of nearby buildings or trees. For an open area, 5 m is usually sufficient. Also, the mast must meet the following criteria:

• strength;
• ease of installation and maintenance of the generator at height;
• sustainability, incl. - to vibration.

It is best to make propellers for a generator in a wing shape for maximum aerodynamic effect. Material – PVC pipes with a diameter of 4 mm or metal. The blades are attached to the engine using a metal head with welded plates according to the number of screws. The optimal number of blades is from 3 to 6.

Attention! The screws are attached at a distance of at least 25 cm from the generator. This is a safety measure. If there is a strong gust, they may break on the body of the device.

Do not despair if the assembled generator does not show the result you expected. Check the calculations, refine and improve the model.

Neodymium magnets. Device and application. Kinds

Almost everyone is familiar with a magnet, because they often played with it in childhood or used it at school to attach thematic materials to the board. Today, magnets are used almost everywhere; they are an essential component for various electronic devices, engines, electric generators, and transformers. Very often, magnets are used to create clips, holders, souvenirs and toys.

The most powerful are neodymium magnets, which are made of a special alloy whose structure includes boron, iron and neodymium. It is these elements that determine their advantages and disadvantages in comparison with magnets made of other materials. It is neodymium magnets that today are universally replacing standard ferrite magnets, finding increasing use.

Neodymium magnets are extremely powerful magnets that are made from rare earth metals. Also known as Neo magnet, NIB or NdFeB. In most cases it is an alloy of neodymium, iron and boron, which forms Nd2Fe14B tetragonal crystal structure.

Neodymium magnets:

• They are distinguished by high resistance to demagnetization.
• They are distinguished by high power of attraction.
• They have a metallic appearance.
• They are extremely in demand; they are used in various fields of electronics, industry, medicine and in everyday life.

The first countries to master the production of neodymium magnets were Japan and the USA.

It was the actively developing potential of these countries that stimulated the emergence of new technologies for creating permanent magnets. The neodymium magnet was first developed by General Motors together with Sumitomo Special Metals in 1982. Currently, these are the strongest permanent magnets from a whole list of commercially available ones.

The magnets have a magnetic energy value that is more than 18 times that of conventional magnets.

The composition of the new magnet was as follows:

• Bor.
• Iron.
• The metal of the lanthanide group is neodymium.

The last element in the new alloy is a rare-earth element; it functions as the main element in the alloy. Boron is present in the alloy in negligible quantities, while iron is a binding element.

https://www.youtube.com/watch?v=G_d2QPhzQPU

Thanks to this composition, magnets have incredibly high adhesive force. Ferrite magnets simply cannot compare with them in this indicator. For example, if you connect two powerful ferrite rings together, then by applying a certain force, you can use your hands to separate them. This simply cannot be done with neodymium magnets. It will be impossible to separate two neodymium magnets connected to each other with bare hands without the use of tools.

The price of the first neodymium magnets, which appeared on the market in the mid-90s of the last century, was quite high. Currently, their cost has decreased slightly, but it still remains high. This is explained by the relatively high rarity of neodymium, including the patent struggle between different manufacturers and developers of magnets.

There are a wide variety of brands and shapes of neodymium magnets. The varied shapes of neodymium magnets are due to their different purposes. So they can have the shape of cones, cylinders, rings, spheres, balls, rectangles, disks and the like. Using the ingredients of neodymium magnets, plastic materials that have magnetic properties are also created. For example, this is magnetic vinyl.

Magnets can be classified according to:

• Magnetic energy.
• Operating temperature range.
• Dimensions.
• Grip strength.

Depending on the brand, magnets differ in operating temperature ranges:

• Brand N (Normal) - up to 80 C, that is, at normal temperatures.
• M (Medium) - up to 100 C, that is, at elevated temperatures.
• H (High) – up to 120 C, that is, at high temperatures.
• SH (Super High) - up to 150 C.
• UH (Ultra High) - up to 180 C.
• EH (Extra High) - up to 200 C.

The numbers that are indicated in the magnet class designation: 40UH, 38SH, 33M, N30 and so on, indicate magnetic energy, it is measured in kJ per cubic meter. This criterion is responsible for the power, that is, the “pull force” that is required to be applied to the magnet in order to lift it from the surface. The higher the magnet designation, the higher the pull-out force will be.

At the same time, the “pull-off force” will also depend on the weight and size of the magnet. For example, a 2520 mm magnet will be an order of magnitude easier to tear off, for example, from a steel sheet than a magnet with an area of ​​405 mm.

Magnets are also differentiated into classes based on the magnitude of their magnetic moment per unit of volume. Classes of neodymium magnets:

• N35-N52;
• N33M-N48M;
• N30H-N45H;
• N30SH-N42SH;
• N30UH-N35UH;
• N28EH-N35EH.

When using neodymium magnets, their features should be taken into account

• The service life of neodymium magnets is at least 30 years; if properly used and stored, it can be an order of magnitude longer. But in some conditions they can be easily damaged and damaged beyond repair. Neodymium magnets are not flexible at all. They can break under a certain load and even crack, including losing their properties.
• Dropping or striking a magnet may cause magnet particles to break off, which may result in reduced adhesion properties. In addition, a strong enough impact can lead to loss of magnet properties. Therefore, dropping neodymium magnets should be avoided, including where parts and components may hit each other or fall.
• The magnetic properties of a magnet when exposed to high temperatures are lost irrevocably. Depending on the current brand of magnet, the heating limit can be in the range of 80-250 degrees Celsius. If heated above the standard temperature, the magnet loses all its properties. Self-demagnetization of neodymium magnets is about 1% over 10 years. This figure is quite high.
• Machining a neodymium magnet is almost impossible. When creating serial samples of magnets, after purchasing them for any purpose, it will be almost impossible to give the magnet any other shape. This is due to the fact that drilling the alloy, cutting with a cutting tool or grinding can cause the alloy to ignite. Including the high temperature that will be generated during friction, will cause a harmful effect on the magnet itself, as well as its properties.

Neodymium magnets are quite widely used in industry; they are used in conducting various experiments and experiments in the field of electrical engineering and physics

• Filters are equipped with powerful magnets that capture small metal particles in liquids or gases.
• Neodymium alloy magnets are also used in the production of souvenirs and toys.
• Magnets, due to their high adhesive force, are used to search for metal objects that lie underground. Today they are actively used by search engines involved in the restoration of wartime equipment.
• Neodymium alloys are used to create magnetic fasteners, which are used to secure various objects.
• For connecting parts of metal structures: strong, but easily separated if necessary.
• For fastening blinds, curtains and other elements associated with windows.
• Creation of levitating interior items and furniture. Recently, many designers, and even ordinary creative people, have been using neodymium magnets to make their tables, stands, trays, and beds truly floating.
• Creation of free energy generators, Tesla generators, magnetic valves, Searle generators, magnetic tunnels and Hall sensors. High-grade magnets are used in the Large Hadron Collider.
• Magnets are widely used in medicine, for example, in magnetic resonance imaging machines, and also to relieve arthritis pain.
• Neodymium magnets can be widely used in everyday life, from plumbing to attaching photographs or a calendar to the refrigerator.
• Magnets are used in the creation of computer hard drives.
• Leveling out small scratches and dents on musical instruments and parts. It is enough just to attach a powerful neodymium magnet to one side of the part, as well as a large steel ball to the other.
• Cleaning technical fluids and motor oils of a car from foreign metal particles and impurities leading to engine wear.
• Magnetization of water. A number of doctors recommend drinking water that has been treated with a magnetic field in order to increase immunity and improve well-being.
• Magnets are used to create lightweight, compact, but very powerful electric current generators, for example, wind turbines , hydroelectric power plants, and other alternative energy facilities.

The advantages of neodymium magnets include:

• The attractive power is tens of times greater than the power of a conventional magnet.
• They are in demand from large manufacturers, but they can also be purchased for household use. Magnets are sold in specialty stores and regular online stores.
• Due to the fairly high power, demagnetization does not occur for a long time. Over 10 years, only 1% demagnetization occurs.
• Possibility of wide application in various industries.
• Light weight and compact dimensions compared to other magnets with the same adhesion force.

The disadvantages of neodymium magnets include:

• Neodymium magnets can be hazardous to health and surrounding products in inexperienced and inept hands. They can damage the upholstery of metal furniture, cars and even walls. They should not be given to children.
• The magnets are very difficult to disengage, which in certain cases is a big drawback.
• Negative impact on the operation of electronics.
• Neodymium magnets cannot withstand strong drops or impacts.
• They lose their properties at relatively high temperatures.

Is it possible to make neodymium magnets with your own hands?

Scientists have long been trying to create super-strong magnets based on various alloys. But most developments had to use materials that could pose a danger to humans. Finally, we managed to obtain a composition based on neodymium.

This rare earth metal does not pose a potential health hazard. Having become acquainted with the unique properties of such a material, many people wonder whether it is possible to make neodymium magnets with their own hands. In theory, this is a technologically complex process.

Or maybe this can be made from recycled materials?

Neodymium magnets: what is this material?

According to scientists, this development took about 20 years of research and testing. When choosing materials, many factors were taken into account: availability, manufacturability, safety, high magnetic properties, resistance to environmental conditions. Scientists considered the use of rare earth metals to be a promising direction. And neodymium was just perfect for these purposes.

Magnets based on it have amazing adhesive strength. Even a small volume of material can support many times its own weight. Magnetic properties last a long time (lose no more than 2% over 10 years of use). Nowadays neodymium magnets can be purchased in specialized stores. Their prices are affordable to almost anyone.

Magnets based on this rare earth metal are designated by the formula Nd2Fe14B. The composition includes neodymium (Nd), iron (Fe), boron (B). The peculiarity of the technology is that this rare earth metal is difficult to isolate in its pure form. The sintering process with the remaining components in powder form must take place in an inert environment. Otherwise, its rapid oxidation occurs with loss of properties.

The technology for normal conditions is complex, so trying to make neodymium magnets with your own hands is impractical. Products are marked during production. The number after the letter N (25, 30, 45) indicates the code. The higher the indicator, the stronger the magnetic properties of the material. The maximum operating temperature of the magnet also depends on the number.

Peculiarities

To prevent exposure to environmental conditions, the magnets are coated with a protective compound. Typically these are two layers of nickel or an improved version with an additional layer of copper in between. Another important feature is that neodymium magnets begin to demagnetize at temperatures above 70 °C. Exceeding the limit values ​​can lead to a complete loss of properties and the alloy turning into just a piece of metal.

The specifics of the material require special safety measures during operation. Thus, neodymium magnets 50x30 mm have an adhesive force of 100 - 115 kg, and 70x50 mm up to 300 kg. If handled carelessly, they can cause harm: pinching fingers, injuring the skin, damaging bones. In the event of an uncontrolled collision of two magnets, the material may crumble and form sharp fragments that can injure the eyes.

Traditionally, they are used in electronic devices and devices where it is necessary to create a constant magnetic field. The properties of the material make it possible to successfully use them when searching for and lifting metal objects from the bottom of reservoirs. Such structures, in addition to the eye for fastening the cable, are equipped with an eye bolt, which is simply necessary, since when screwed in, it allows you to separate two strongly adhered surfaces.

Magnets are available in sizes from 1 to 120 mm in diameter and in different thicknesses and shapes. The thinnest of them are widely used in the leather goods and furniture industries. They can be found in funny toys and devices for hanging various utensils. Powerful magnets are indispensable for filtering bulk and liquid materials. They are used to catch metal impurities and foreign objects in the conveyor flow.

The high adhesive force encourages people to use them to achieve “savings” when using water and gas. By purchasing neodymium magnets for counters, they thus try to stop or slow down the rotation of their mechanism. This possibility theoretically exists in devices where steel elements are used internally. A powerful magnet placed in a specific location on the housing can slow down the rotation of the impeller.

Industrial technology, in addition to sintering the mass into an alloy, also involves a complex process of magnetization of the resulting substance, which is inaccessible for home conditions. Very powerful force fields are used for this. If you have a great desire to obtain neodymium magnets yourself, you can do this yourself by disassembling “obsolete” electronics.

In some old hard drives you can find one or two small elements inside. It is not advisable to try to drill or crush such magnets. The surface protective layer is damaged, the material reacts with the environment and loses its properties. In addition, as experts say, the shavings are highly flammable and can ignite surrounding surfaces.

Powerful magnets

> Theory > Powerful magnets

Even in ancient China, attention was paid to the attractive properties of some metals. This physical phenomenon is called magnetism, and materials that have this ability are called magnets.

Now this property is actively used in radio electronics and industry, and especially powerful magnets are used, among other things, for lifting and transporting large volumes of metal. The properties of these materials are also used in everyday life - many people know magnetic cards and letters for teaching children.

What kind of magnets there are, where they are used, what neodymium is, this text will tell you about it.

Types of magnets

In the modern world, they are classified into three main categories based on the type of magnetic field they create:

• permanent, consisting of a natural material that has these physical properties, for example, neodymium;
• temporary, possessing these properties while in the field of action of a magnetic field;
• Electromagnets are coils of wire on a core that create an electromagnetic field when energy passes through the conductor.

In turn, the most common permanent magnets are divided into five main classes, according to their chemical composition:

• ferromagnets based on iron and its alloys with barium and strontium;
• neodymium magnets containing the rare earth metal neodymium in an alloy with iron and boron (Nd-Fe-B, NdFeB, NIB);
• samarium-cobalt alloys, which have magnetic characteristics comparable to neodymium, but at the same time a wider temperature range of application (SmCo);
• Alnico alloy, also known as UNDC, this alloy is characterized by high corrosion resistance and a high temperature limit;
• magnetoplasts, which are a mixture of a magnetic alloy with a binder, this allows you to create products of various shapes and sizes.

Ferrites

Alloys of magnetic metals are brittle and fairly cheap products with average qualities. It is usually an alloy of iron oxide with strontium and barium ferrites. The temperature range for stable operation of the magnet is not higher than 250-270°C. Specifications:

• coercive force – about 200 kA/m;
• residual induction – up to 0.4 Tesla;
• average service life is 20-30 years.

What are neodymium magnets

These are the most powerful of the permanent ones, but at the same time they are quite fragile and not resistant to corrosion; these alloys are based on the rare earth mineral - neodymium. This is the strongest permanent magnet.

Characteristics:

• coercive force – about 1000 kA/m;
• residual induction – up to 1.1 Tesla;
• average service life is up to 50 years.

Their use is limited only by the low limit of the temperature range; for the most heat-resistant brands of neodymium magnet it is 140°C, while less resistant ones are destroyed at temperatures above 80 degrees.

Samarium-cobalt alloys

Possessing high technical characteristics, but at the same time very expensive alloys.

Characteristics:

• coercive force – about 700 kA/m;
• residual induction – up to 0.8-1.0 Tesla;
• average service life is 15-20 years.

They are used for difficult working conditions: high temperatures, aggressive environments and heavy loads. Due to their relatively high cost, their use is somewhat limited.

Alnico

A powder alloy of cobalt (37-40%) with the addition of aluminum and nickel also has good performance characteristics, in addition to the ability to retain its magnetic properties at temperatures up to 550°C. Their technical characteristics are lower than those of ferromagnetic alloys and are:

• coercive force – about 50 kA/m;
• residual induction – up to 0.7 Tesla;
• average service life is 10-20 years.

But, despite this, it is this alloy that is most interesting for use in the scientific field. In addition, the addition of titanium and niobium to the alloy helps to increase the coercive force of the alloy to 145-150 kA/m.

Magnetic plastics

They are used mainly in everyday life for making magnetic cards, calendars and other small things; the characteristics of the magnetic field decrease slightly due to the lower concentration of the magnetic composition.

These are the main types of permanent magnets. The principle of operation and application of an electromagnet differs somewhat from such alloys.

Interesting. Neodymium magnets are used almost everywhere, including in design to create floating structures, and in culture for the same purposes.

Electromagnet and demagnetizer

If an electromagnet creates a field when passing through the turns of the winding of electricity, then the demagnetizer, on the contrary, removes the residual magnetic field. This effect can be used for various purposes.

For example, what can be done with a demagnetizer? Previously, the demagnetizer was used to demagnetize the playback heads of tape recorders, television picture tubes and perform other similar functions.

Today it is often used for somewhat illegal purposes, to demagnetize meters after using magnets on them. In addition, this device can and should be used to remove residual magnetic fields from instruments.

The demagnetizer usually consists of an ordinary coil, in other words, in terms of design, this device completely replicates an electromagnet. An alternating voltage is applied to the coil, after which the device from which we remove the residual field is removed from the demagnetizer's coverage area, after which it turns off

Important! Using a magnet to “twist” the meter is illegal and will result in a fine. Improper use of the demagnetizer can lead to complete demagnetization of the device and its failure.

Making your own magnet

To do this, it is enough to find a metal bar made of steel or other ferroalloy; you can use the composite core of the transformer, and then make a winding. Wind several turns of copper winding wire around the core. For safety, it is worth including a fuse in the circuit. How to make a powerful magnet? To do this, you need to increase the current strength in the winding; the higher it is, the greater the magnetic force of the device.

When the device is connected to the network and electricity is supplied to the winding, the device will attract metal, that is, in fact, it is a real electromagnet, albeit of a somewhat simplified design.

In the modern world, magnetic field energy is widely used. Both in industry, radio electronics and electrical engineering, and for domestic purposes. Dozens of different devices have been created to generate a magnetic field, and the natural properties of minerals are also used.

The most widely used permanent magnet is the neodymium magnet. Its use and widespread use is due to both its cost and excellent technical characteristics. Its disadvantages are: a tendency to corrosion and fear of high temperatures. For this reason, in difficult operating conditions, other types are used that do not have these limitations.

Wind generator with neodymium magnets

Neodymium magnet is a rare earth metal that is resistant to demagnetization and has the ability to magnetize certain materials. Used in the manufacture of electronic devices (computer hard drives, metal detectors, etc.), medicine and energy.

Neodymium magnets are used in the manufacture of generators operating in various types of installations that generate electric current.

Currently, generators made using neodymium magnets are widely used in the manufacture of wind turbines.

Main characteristics

In order to determine the feasibility of manufacturing a generator using neodymium magnets, you need to consider the main characteristics of this material, which are:

• Magnetic induction B is a strength characteristic of a magnetic field, measured in Tesla.
• Residual magnetic induction Br is the magnetization possessed by a magnetic material when the external magnetic field strength is zero, measured in Tesla.
• Coercive magnetic force Hc - determines the resistance of a magnet to demagnetization, measured in Amperes/meter.
• Magnetic energy (BH)max - characterizes how strong the magnet is.
• Temperature coefficient of residual magnetic induction Tc of Br – determines the dependence of magnetic induction on the ambient temperature, measured as a percentage per degree Celsius.
• Maximum operating temperature Tmax - determines the temperature limit at which the magnet temporarily loses its magnetic properties, measured in degrees Celsius.
• Curie temperature Tcur - determines the temperature limit at which a neodymium magnet is completely demagnetized, measured in degrees Celsius.

The composition of neodymium magnets, in addition to neodymium, includes iron and boron and depending on their percentage, the resulting product, the finished magnet, differs in classes, differing in their characteristics given above. A total of 42 classes of neodymium magnets are produced.

The advantages of neodymium magnets that determine their demand are:

• Neodymium magnets have the highest magnetic parameters Br, Hsv, Hcm, VN.
• Such magnets have a lower cost compared to similar metals containing cobalt.
• They have the ability to operate without loss of magnetic characteristics in the temperature range from – 60 to + 240 degrees Celsius, with a Curie point of +310 degrees.
• From this material it is possible to make magnets of any shape and size (cylinders, disks, rings, balls, rods, cubes, etc.).

Wind generator on neodymium magnets with a power of 5.0 kW

Currently, domestic and foreign companies are increasingly using neodymium magnets in the manufacture of low-speed electric current generators. Thus, Salmabash LLC, Gatchina, Leningrad Region, produces similar permanent magnet generators with a power of 3.0-5.0 kW. The appearance of this device is shown below:

The generator housing and covers are made of steel, later coated with paint and varnish materials. The housing is equipped with special fastenings that allow you to secure the electrical device to the supporting mast. The inner surface is treated with a protective coating that prevents metal corrosion.

The generator stator is made of electrical steel plates.

The stator winding is made of enamel wire, allowing the device to operate for a long time at maximum load.

The generator rotor has 18 poles and is mounted in bearing supports. Neodymium magnets are placed on the rotor rim.

The generator does not require forced cooling, which is carried out naturally.

Technical characteristics of the 5.0 kW generator:

• Rated power – 5.0 kW;
• Rated frequency – 140.0 rpm;
• Operating rotation range – 50.0 – 200.0 rpm;
• Maximum frequency – 300.0 rpm;
• Efficiency – not less than 94.0%;
• Cooling – air;
• Weight – 240.0 kg.

The generator is equipped with a terminal box through which it is connected to the electrical network. The protection class corresponds to GOST 14254 and has a degree of IP 65 (dust-proof design with protection from jets of water).

The design of this generator is shown in the figure below:

where: 1-body, 2-bottom cover, 3-top cover, 4-rotor, 5-neodymium magnets, 6-stator, 7-winding, 8-coupling half, 9-seals, 10,11,12-bearings, 13 - terminal box.

Advantages and disadvantages

The advantages of wind generators made using neodymium magnets include the following characteristics:

• High efficiency of devices, achieved by minimizing friction losses;
• Long service life;
• No noise or vibration during operation;
• Reduced costs for installation and installation of equipment;
• Autonomy of operation, allowing operation without constant maintenance of the installation;
• Possibility of self-production.

The disadvantages of such devices include:

• Relatively high cost;
• Fragility. Under strong external influence (impact), a neodymium magnet can lose its properties;
• Low corrosion resistance, requiring special coating of neodymium magnets;
• Dependence on operating temperature – when exposed to high temperatures, neodymium magnets lose their properties.

How to make it yourself

A wind generator based on neodymium magnets differs from other generator designs in that it can easily be made independently at home.

As a rule, they take as a basis a car hub or pulleys from a belt drive, which are pre-cleaned if they are used spare parts and prepared for work.

If it is possible to manufacture (turn) special discs, it is better to choose this option, because... in this case, there is no need to adjust the geometric dimensions of the wound coils to the dimensions of the workpieces used.

Neodymium magnets should be purchased, for which you can use the Internet or the services of specialized organizations.

One of the options for manufacturing a generator on neodymium magnets, using disks specially made for these purposes, is proposed for consideration by V.G. Yalovenko. (Ukraine). This generator is manufactured in the following sequence:

1. Two disks with a diameter of 170.0 mm with a central hole and a keyway are machined from sheet steel.
2. The disk is divided into 12 segments, and corresponding markings are made on its surface.
3. Magnets are glued into the marked segments so that their polarity alternates. To avoid errors (in polarity), it is necessary to mark them before applying the sticker.
4. The second disk is made in a similar way. The result is the following construction:

1. The surface of the claims is filled with epoxy resin.
2. 12 coils of 55 turns each are wound from wire (enamel wire) of PETV brand or equivalent, with a cross-section of 0.95 mm2.
3. A template is made on a sheet of plywood or paper that corresponds to the diameter of the disks used, which is also divided into 12 sectors.

The coils are placed in marked segments, where they are fixed (insulating tape, adhesive tape, etc.) and disconnected sequentially from each other (the end of the first coil is connected to the beginning of the second, etc.). the result is the following construction

1. A matrix is ​​made from wood (board, etc.) or plywood, in which coils laid according to a template can be filled with epoxy resin. The depth of the matrix must correspond to the height of the coils.
2. The coils are placed in a matrix and filled with epoxy resin. The result is the following workpiece:

1. A hub with a mounting unit for the shaft of the manufactured generator is made from a steel pipe with a diameter of 63.0 mm. The shaft is mounted on bearings installed inside the hub.
2. A rotating mechanism is made from the same pipe, ensuring the orientation of the generator in accordance with wind flows.
3. Manufactured spare parts are put on the shaft. The result is the following design, plus a rotating mechanism:

1. The design should rigidly mount the stator (a blank with windings filled with epoxy resin), on the one hand, and not impede the rotation of the rotor (discs with non-dimium magnets).
2. Wind generator blades are made from pipes (polyethylene, propylaea, etc.) used for laying water supply or sewerage networks. To do this, the pipe is cut to the required length, after which it is cut and the blanks are given the appropriate shape.
3. The tail of the wind turbine is being manufactured. For this, any sheet material (plywood, metal, plastic) can be used, after which the shank is attached to the assembled structure, on the side opposite to the attachment of the blades. The result is the following construction:
4. • The assembled installation is installed in the place provided for this purpose.
   • A load is connected to the generator terminals.

   The design of a wind generator using neodymium magnets can be different, it all depends on the available spare parts and the technical capabilities of the person who decides to make such a device on their own.

How to get magnetic water and how to take it

Now many readers know that magnetizing water significantly improves its quality. In the natural environment, this occurs when water passes through layers of earth's rocks.

When charged with magnetic energy, it acquires many useful biological and chemical properties.

They activate the rate of chemical reactions in the human body, metabolic processes, improve health, give strength, and promote longevity. How to get magnetic water and how to take it.

What’s impressive is that the process of magnetizing water at home does not require additional costs or the use of chemicals. Water, being in an induction magnetic field, acquires biological activity that improves human health.

• You can read about the benefits of magnetic water by following the link.

How to get magnetic water at home

Magnetic water is easy and simple to make yourself, at home. After all, as soon as ordinary water crosses the magnetic lines of force, it immediately turns into magnetized water, the healing properties of which last up to 48 hours!

To prepare water, you will need a small plastic or glass funnel, to the spout of which two magnets are attached on opposite sides, with the sides attracting to each other.

Or you can put two magnetic rings on the spout. By passing water through a funnel, you will obtain magnetic water from ordinary water. If the magnets are small, then the magnetization of water can be enhanced by pouring water through the funnel several times. And you will spend only 2-3 minutes on this procedure.

Or use a purchased funnel with magnets built inside.

What magnets to use for preparing water

Ferrite magnets are probably familiar to older generations. These are ordinary black magnets, which contain, in addition to iron, cobalt oxide, strontium and barium. They are durable, do not demagnetize for a long time, are not expensive, and are not afraid of moist air. But they are very fragile and have a weak magnetic field.

Neodymium magnets have replaced ferrite magnets; they are made using iron, boron and neodymium. Neodymium is an expensive metal. They usually have a nickel coating on top. Neodymium magnets are more expensive, more durable, and have greater adhesive force compared to ferrite magnets.

To prepare magnetic water, it is better to use neodymium magnets, the magnetic material of which is considered a material of the 21st century. Today, these magnets are considered the best, with a more powerful and wider magnetic field.

How to determine the north pole of a magnet

To determine the pole of a magnet, use a compass. Slowly bring the magnet to it with the flat side, as soon as the needle stops shaking and is steady, look carefully: if the North needle of the compass turns towards the magnet, then this side of the magnet is North.

Also check the opposite side of the magnet, you will see that the South arrow of the compass has turned towards it. Make a mark on the magnet, marking its south pole.

Another method for determining the pole. Hang the magnet by a thread (there should be no metal objects nearby), the south pole of the magnet will turn to the south, and the north pole will point to the north.

And one more way to quickly determine the poles of a magnet. Drop a drop of vegetable oil into a plate and place the magnet on it edgewise, it will immediately turn its southern plane to the south, and its northern plane will point to the north.

Why do you need to know the poles of a magnet?

Considering the polarity of the magnet, we can prepare magnetic water either “south” or “north” or mixed.

Northern magnetic water. According to scientists, “northern water” has bactericidal and disinfecting properties. Typically, this water is used to treat viral infections, infectious skin diseases, and inflammatory eye diseases.

“Southern water” is often used when the body’s vitality is lost or overwork; it has stimulating properties.

Mixed water or “south-north” . Of course, it is better to prepare mixed water, which would improve health and add energy.

How to determine magnetic field induction

To obtain healing water, it is necessary to keep it between two poles, with a magnetic field strength = 3200 Gauss. How to determine magnetic field induction? Magnetic induction is determined in teslas (T) and gassles (Gs) - the names come from the names of the scientists who discovered them (1 Gs = 10-4 T.)

This is for general information, since I noticed that in some sources the induction of a magnet is expressed in T, in others - in G, I thought that there was an error hiding somewhere and began to look into it. It turned out that both were correct.

In order not to delve into the physical jungle, people far from physics are offered a simple method for selecting a magnet with a magnetic field induction of 3200 Gauss. It turns out that magnets can be selected according to diameter and thickness. So, an induction of 3200 Gauss will be created by 2 neodymium magnets, diameter = 11.5 mm and thickness = 3 mm.

How to make high quality mixed water

Now, armed with some knowledge, let’s prepare magnetic water according to science. For this, we will need two neodymium magnets with the pole marks described above.

Place one magnet on the table so that its south pole is at the bottom and its north pole is at the top. Place a glass of 250 ml water on it. Cover the glass with a regular canning lid with a magnet facing the water at the south pole.

This is the science, it took a long time to describe everything, but making a homemade device to obtain magnetic water is very simple. After 10 minutes, with this magnetic field induction, high quality water is ready for consumption.

Now you know how to get “northern” magnetic water? That's right, you need to turn the magnet on the lid over with a different plane. And if you need “southern” magnetic water, then turn over the magnet that lies under the glass.

In our house we only had ferrite magnets with a weak magnetic field. Therefore, I decided to prepare magnetic water, keeping it for 1-2 hours.

To make the glass on the magnet stand more firmly, do this: cover the bottom magnet with a lid and cover the glass with a second lid with a magnet:

In general, experts do not recommend using metal when magnetizing water, since the magnetic field is discharged. But in the case of neodymium magnets (d = 11.5 mm), since their diameter is small, the metal cover helps distribute the magnetic field over the entire surface of the glass.

Therefore, powerful neodiom magnets are recommended for magnetization.

When magnetizing water, magnets should not be immersed in the water; they should be on the outside of the glass. Try to keep your water magnetization device away from household electrical appliances.

How to take water

The healing properties of magnetic water last for two days. There is no need to store water for future use. It is better to add it as it is used up into a container located under the magnetic power lines.

Magnetic water is taken on an empty stomach, a few minutes before meals; you can drink water during meals. You need to drink up to 1.5 to 2 liters of magnetized water per day, 4-5 times a day. Water is taken in courses of up to 1 - 1.5 months. After a break is taken, it is recommended to conduct 2-3 courses per year.

If you have stones in the kidneys or gall bladder, drink magnetic water in small portions. Here, for example, is how Professor V. Klassen recommends taking water for kidney stone disease, both for the purpose of prevention and treatment: three times a day, on an empty stomach, take 150 ml of magnetic water.

The course of treatment is one and a half months.

For the purpose of prevention, to support the body, the amount of water taken can be reduced.

Now on sale you can find various devices and devices for magnetizing water, the simplest of them: magnetic funnels, mugs, stands, which are not expensive.

Of the listed devices, mixed magnetic water can only be obtained using two magnets.

Is it possible to make a neodymium magnet with your own hands?

Neodymium magnet is a type of permanent rare earth magnet that is made by fusing metals such as neodymium, boron and iron. Many people are interested in the question: “Is it possible to make a neodymium magnet with your own hands?”

It is almost impossible to set up the production of neodymium magnets at home, since this requires special equipment, melting furnaces, chemical raw materials, as well as powerful electromagnets for magnetizing the resulting alloy.

If you need neodymium magnets for your own purposes, then it will be much faster and cheaper to purchase them in our company’s online store.

Neodymium Magnet Manufacturing Process

Today, a special powder technology is widely used for the manufacture of neodymium magnets, which makes it possible to create three types of products: sintered, cast and pressed. In general, the manufacturing process for neodymium magnets is as follows:

• Iron, neodymium and boron in a certain proportion are fused together in a vacuum induction furnace;
• The resulting alloy is crushed and ground to a powder;
• The powder is placed in special molds and pressed in a magnetic field, at this stage the direction of magnetization is set;
• The resulting workpieces are subjected to sintering at temperatures from 1000 to 1100 degrees;
• Then the products are mechanically polished and annealed;
• For magnetization, magnets are placed in a special magnetizing installation;
• To ensure resistance to corrosion, the magnets are coated with a layer of nickel or zinc.

The operations of fusion, pressing, and sintering are carried out in a vacuum or in an environment with inert gases. Thus, the production of neodymium magnets is a rather complex high-tech process that requires special training and expensive equipment.

Where can you buy a quality neodymium magnet?

The catalog of our online store presents a wide range of high-quality neodymium magnets from leading Russian manufacturers. Magnets from a Russian manufacturer are considered to be among the highest quality and strongest, and are popular all over the world. In the catalog you will find magnets of all available shapes and sizes:

Make a powerful magnet with your own hands. How are neodymium magnets made?

Man first became acquainted with magnets in ancient times. However, very quickly this natural stone ceased to satisfy people's needs. It was then that the technology for making magnets was developed. Of course, a lot of time has passed since then.

Technology has changed significantly, and now it is possible to make a magnet at home. You don't need any special skills or knowledge to do this. It is enough to have all the necessary materials and tools at hand.

So, making a magnet looks like this.

Soft magnetic materials

All materials capable of magnetization can be divided into soft magnetic and hard magnetic. There is a significant difference between them. Thus, soft magnetic materials do not retain magnetic properties for long.

You can conduct an experiment: run iron bars over a strong magnet several times. As a result, the material will acquire the properties of attracting other metal objects. However, the production of one with these abilities is impossible in this case.

Hard magnetic materials

Such materials are obtained by magnetizing an ordinary piece of iron. In this case, the properties are preserved much longer. However, they completely disappear when the object hits a sufficiently hard surface. They are also destroyed if the material is heated to 60 degrees.

Finally

Making permanent magnets at home is a fairly simple process. However, you should be careful when using certain schemes.

Neodymium is considered the most powerful permanent magnet. You can make it at home, but this requires a piece of rare earth metal - neodymium. In addition, an alloy of boron and iron is used. Such a workpiece is magnetized in a magnetic field. It is worth noting that such a product has enormous power and loses only 1 percent of its properties over a hundred years.

There are several ways to make a magnet at home. The first and second methods are suitable for simple home experiments and for showing to children. The third and fourth methods are somewhat more complicated and require care and caution.

Options for making simple magnets with your own hands

Method 1

To create a magnet you will need the simplest materials at hand:

• Copper wire.

How to strengthen a magnet at home

Employees of the site p-magnit.ru are sometimes asked about how to make a neodymium magnet with your own hands. Let's try to figure out how possible this is, and what the process of producing such products is all about.

So, the devices we sell consist of an alloy that is 70% iron and almost 30% boron. Only a fraction of a percent in its composition is made up of the rare earth metal neodymium, natural deposits of which are extremely rare in nature. Most of them are in China; they are found in only a few other countries, including Russia.

Before making neodymium magnets, manufacturers create molds for them from sand. Then the tray with the molds is doused with gas and subjected to heat treatment, due to which the sand hardens and retains the future outlines of the metal workpiece on its surface. Hot metal will later be placed in these forms, from which, in fact, the necessary products will be obtained.

Now let's directly look at how a neodymium magnet is made. Unlike ferromagnetic products, the metal here is not melted, but sintered from a powder mixture placed in an inert or vacuum environment.

Then the resulting magnetoplast is pressed while simultaneously exposing it to an electromagnetic field of a certain intensity. As you can see, even at the initial stage of production, it is noticeable that the question of how to make neodymium magnets at home sounds inappropriate.

The operations and equipment used are too complex. Creating such conditions at home is hardly possible.

After the workpieces are removed from the molds, they are subjected to mechanical processing - they are carefully polished, then they are fired to improve the coercive force of the products.

Finally, we come to the last steps, which will help to finally answer the question of how neodymium magnets are made. The sintered NdFeB alloy is again machine-finished using a special tool. During operation, a cooling lubricant is used to prevent overheating or ignition of the powder.

A protective coating is applied to the magnets. This is due, firstly, to the fact that sintered metals are quite fragile and need to be strengthened, and, secondly, the metal will be protected from corrosion processes and other environmental influences.

So manufacturers worry in advance about how to make a neodymium magnet stronger and more durable. The coating can be copper, nickel, zinc. In the last phase of the production process, magnetization is applied through a strong magnetic field.

Then they are sent to the warehouse, and from there to customers.

So, after we examined the production process in more or less detail, it became clear that we probably shouldn’t seriously ask the question “how to make a neodymium magnet at home.” After all, this requires not only certain knowledge, but many complex units.

How to completely demagnetize a neodymium magnet

Neodymium magnets are very popular in modern industry and in solving a number of everyday problems. If the buyer (for example) chose strong magnets for delivery in St. Petersburg, but violated the storage or transportation conditions, as a result of which they stuck together, it may be necessary to carry out a demagnetization procedure. The same action may be necessary in other cases when it is necessary for the product to lose its qualities.

The process can be carried out in various ways, including using factory equipment, and it is necessary to decide how to demagnetize a neodymium magnet taking into account your capabilities.

Methods for demagnetizing a magnet

Loss of the ability to attract metal objects can occur both naturally and during a number of actions. Subject to the rules of operation and storage, the qualities of neodymium elements are maintained for 100 years or more, and ferrite analogues continue to attract metal for 8-10 years. Degaussing neodymiums naturally is not practical if the procedure is to be performed on a new item.

Product heating

This method is used both in industrial and domestic conditions: if the magnet is made of a standard alloy of neodymium with boron and iron, it will lose its properties when placed in water boiling at 80 degrees Celsius or in case of contact with a surface heated to the specified temperature.

If we are talking about a product with increased resistance to thermal shocks, it is unlikely that it will be possible to perform the procedure at home: the demagnetization temperature of neodymium magnets with such properties is 200 degrees Celsius.

To carry out the procedure in such cases, special industrial equipment is used.

Mechanical Actions

Neodymium can lose its qualities as a result of a strong directed impact, for example, an impact: this material has a powder structure that is destroyed when dropped from a height or when exposed to impact equipment. In addition, demagnetization can occur accidentally during the process of drilling or cutting a magnet: this is due to excessive mechanical pressure or an increase in the temperature of the product without forced cooling.

Treatment with external magnetic influence

Most often, if it is possible to use industrial equipment of increased power, another magnet is used, which allows the formation of a field with an induction force of about 4 Tesla. A neodymium magnet is demagnetized in a matter of seconds, so this method, despite its technological complexity, is characterized by the fastest possible result.

How to magnetize demagnetized neodymium

If the demagnetization of an element occurs accidentally, and it is necessary to return the product to its properties, it is impossible to do this at home. Restoring a neodymium magnet requires the use of a product that can create a very powerful field, and this requires the use of professional equipment used to create such items.

Usually, if you need to return the magnetization properties for a specific element, you contact a factory that specializes in the production of such products.

Is there anything I can do to make the magnet stronger?

If neodymium used for household purposes has become demagnetized, often a more appropriate solution would be to purchase a new element. The cost of magnetization work varies depending on the required properties and pricing policy of a particular production.

Application of neodymium magnet

These products are available in various shapes and sizes and are used for the following tasks:

• Creating a clamping effect, fixing metal elements to each other. Using neodymium magnets, you can attach an antenna, license plate, plate, other metal part, device or entire mechanism.
• Filtration of oil systems in cars and other equipment: neodymium magnets allow you to easily and quickly remove metal shavings.
• Creation of magnetic locks and fasteners used in industrial sectors and household purposes.
• Search work related to the search for metal objects (search for treasures, historical values, weapons, mine clearance work, etc.).
• Restoring other magnetic elements: using a neodymium element, you can create a magnetic field that will return the product to its ability to attract metal.
• Deleting information recorded on floppy disks, disks, flash drives and other electronic media for security purposes.
• Creation of devices for universal use (hangers, stirring devices, compasses, etc.).
• Construction of current generators that can be used as experimental models or devices suitable for domestic use.
• Making jewelry: Neodymium can come in different shapes and sizes, and beads made from this material are often given a chrome finish and can be painted in different colors.
• Treatment of water using magnetic influence, as a result of which the formation of scale is reduced, and the liquid itself acquires an improved taste and smell.
• Fuel conditioning, which allows you to reduce fuel consumption for cars and motorcycles.
• Sorting small metal items that need to be removed from a variety of non-metal items.

Conclusion

Neodymium magnets are products that are widely used in commercial, industrial and household applications, they are characterized by high load capacity, excellent attractive properties and durability.

Before demagnetizing neodymium magnets, it is important to make sure that you have the necessary equipment: this requires either an industrial installation or a device for heating to at least 80 degrees.

Magnetizing products that have lost their quality is rarely advisable, but if necessary, you can order the procedure by contacting the manufacturer.
