Application of neodymium magnets

Applications of neodymium magnets | Ural Magnit

Before we look at the scope of application of neodymium magnets, let's look at history. The neodymium magnet owes its appearance to the Austrian chemist Karl Auer von Welsbach, who in 1885 discovered the new chemical element Neodymium and described its properties.

But it took many years to develop an industrial method for producing Neodymium.

The industrial extraction of Neodymium began only in 1925, the scope of application of this chemical element has a very wide range, the metallurgical industry, agriculture, medicine and much more, but we will consider only a small segment of the use of this element - these are neodymium magnets and their scope.

Where is neodymium magnet used?

Due to the low cost of a neodymium magnet, the power of its magnetic field and high resistance to demagnetization, the scope of application of neodymium magnets is very diverse: science, construction, energy, industry, printing, education, creativity.

Neodymium magnets are widely used in generators, since the strength of the magnet used directly affects the power of the generator. In modern medicine, they are used in magnetic resonance imaging machines. Neodymium magnets are used in oil filters to remove metal shavings from petroleum products.

Modern metal detectors also use these magnets.

Use of neodymium magnets in everyday life

The use of neodymium magnets in everyday life also occupies a huge niche. For example, these magnets are widely used in the production of hard drives in modern computers. They are also used in DVD drives in the shape of a small cube.

Neodymium magnets are very often used in the manufacture of speakers for smartphones, mobile phones, tablets, headphones, radios, speakers and other types of radio systems.
to increase speaker power. The only disadvantage of neodymium magnets is the partial loss of magnetic energy at high temperatures.

This excludes their use in electronics, where the coefficient of generated thermal energy is too high. However, the presence of different classes of neodymium magnets allows them to be used at temperatures up to 200 degrees Celsius.

Neodymium magnet – MAGNET STANDARD

Magnets are used in many areas of human life, including everyday life - they are found in almost all home appliances. Today, neodymium magnets are the most commonly used. They differ from ferrite ones by a higher (approximately 10 times greater) level of residual magnetization.

 This material is an alloy:

• gland;
• boron;
• neodymium (a metal from the lanthanide group).

The last rare earth element is the main element in the composition. Boron is present in negligible quantities, and iron is a binding component.

Thanks to this composition, the necessary physical characteristics are achieved.

• Incredibly high adhesive force, which cannot be compared with the capabilities of ferrite magnets. For example, if connected ferrite rings can be difficult to disengage with your hands, then with neodymium rings everything is not so simple. It will not be possible to separate them without tools.
• High resistance to demagnetization. Every 10 years of operation, the material loses a negligible percentage of its beneficial properties (up to 2%). This factor has led to its use in the production of medical equipment.

Classification. Variety of shapes and markings

Neodymium magnets vary in adhesive strength, magnetic energy level, operating temperature range, and shape.

Traction force depends on:

• plane and surface area;
• degree of purity;
• properties of constituent metals;
• sizes;
• direction of the magnetic field;
• air temperature and humidity.

By increasing the dimensions and the parameters of cleanliness and smoothness, the adhesion force increases. Note that for rusted or uneven materials it will be significantly less even at the same level of magnetic energy.

Depending on the purpose, neodymium magnets are produced in various shapes: disks, rectangles, spheres, rings, cylinders, etc. Plastic materials, for example, vinyl, are also produced.

The marking of each product contains letters and numbers that indicate the level of magnetic energy, for example, “N38”. This indicator depends on the purity and properties of the alloy elements.

The brand of the product will also indicate the operating temperature range, for example:

• N40 - 80 °C;
• 42SH - 150 °C;
• 38EH - 200 °C.

The price for this material is quite high. Particularly powerful models can cost several thousand rubles. This price list is determined by the rarity of the main element of the alloy and the patent struggle of developers.

Production of neodymium magnets

The product is manufactured in ovens using special equipment. The process takes place either in a vacuum or in an atmosphere of inert gas.

Main stages of production:

1. the ingredients are ground to a powdery state;
2. the workpiece is given the desired shape using a press;
3. direct the magnetic field vector;
4. the workpiece is processed in a furnace with simultaneous magnetization.

This is what mass production looks like. When making individual orders, deviations from the general algorithm are possible.

Features of storage and operation

The service life of neodymium magnets with proper use is 30 years or more, but if handled carelessly they easily deteriorate.

The fact is that the material is not flexible at all. Under load it breaks and cracks. A fall or impact can lead to chips - the adhesion properties are reduced. A sufficiently strong impact can deprive the product of its magnetic properties even without visible damage. Therefore, falls and use in mechanisms with parts that come into contact during movement should be avoided.

Another extremely important point is that when the material is heated above the permissible value, the magnetic properties are irretrievably lost. It is almost impossible to process the finished product in any way or give it a different shape. Grinding, cutting or drilling may cause the alloy to catch fire. The thermal energy released during friction reduces the adhesion force.

If storage and operation are properly organized, the material loses only 1 to 2% of magnetization over 10 years.

Application of neodymium magnets

High adhesive force determines a wide range of applications for products. They are used in industry, everyday life, medicine and many other areas.

• The material is indispensable in the production of filter devices. Due to high magnetic indicators, the lion's share of metal impurities is retained on the surface.
• Magnets have found application in medicine. They are part of magnetic resonance imaging machines. These devices are used to relieve arthritis pain.
• The high level of magnetic energy of neodymium magnets is ideal for prospecting work. Metal detectors based on them do an excellent job. They are actively used by weapons and equipment restorers.
• Replacing old magnets in a generator or motor will significantly increase power. The engine will work better, the speed will increase, and energy consumption will decrease.
• Not long ago, this material found a place in the production of souvenirs and advertising stands.
• At the household level, magnets are used, for example, in plumbing fixtures, all kinds of appliances, or as souvenirs on the refrigerator.

Generator with neodymium magnets. Perpetual motion machine on neodymium magnets

The fact that a generator using neodymium magnets, for example a wind generator, is useful is no longer in doubt. Even if it is not possible to provide energy to all the appliances in the house in this way, it will still show its advantage with prolonged use. Making the device yourself will make operation even more economical and enjoyable.

Characteristics of neodymium magnets

But let's first find out what magnets are. They appeared not so long ago. It has been possible to purchase magnets in stores since the nineties of the last century. They are made of neodymium, boron and iron. The main element, of course, is neodymium. It is a metal of the lanthanide group, with the help of which magnets acquire enormous adhesive force. If you take two large pieces and pull them together, it will be almost impossible to separate them.

Mostly, of course, there are miniature species on sale. In any gift shop you can find balls (or other shapes) made of this metal. The high price of neodymium magnets is explained by the complexity of extracting raw materials and the technology of their production. If a ball with a diameter of 3-5 millimeters will cost only a few rubles, then for a magnet with a diameter of 20 millimeters and above you will have to pay 500 rubles or more.

Neodymium magnets are produced in special furnaces, where the process occurs without oxygen, in a vacuum or an atmosphere with an inert gas. The most common are magnets with axial magnetization, in which the field vector is directed along one of the planes where the thickness is measured.

The characteristics of neodymium magnets are very valuable, but they can easily be damaged beyond repair. So, a strong blow can deprive them of all their properties. Therefore, you need to try to avoid falls. Also, different species have their own temperature limit, which varies from eighty to two hundred and fifty degrees. At temperatures above the limiting temperature, the magnet loses its properties.

Proper and careful use is the key to maintaining quality for thirty years or more. Natural demagnetization is only one percent per year.

Finished vertically oriented wind generator

There has been renewed interest in wind turbines, especially in recent years. New models have appeared, more convenient and practical.

Until recently, horizontal wind generators with three blades were mainly used. And vertical views did not extend due to the heavy load on the wind wheel bearings, which resulted in increased friction that absorbed energy.

But thanks to the use of the principles of magnetic levitation, a wind generator on neodymium magnets began to be used in a vertically oriented manner, with pronounced free inertial rotation. Currently, it has proven its higher efficiency compared to horizontal.

An easy start is achieved thanks to the principle of magnetic levitation. And thanks to the multi-polarity, which gives the rated voltage at low speeds, it is possible to do away with gearboxes completely.

Some devices are capable of starting to work when the wind speed is only one and a half centimeters per second, and when it reaches only three to four meters per second, it can already be equal to the generated power of the device.

Application area

Thus, a wind generator, depending on its power, can provide energy to different buildings.

1. City apartments.

2. Private houses, cottages, shops, car washes.

3. Billboards, traffic lights, streets.

4. Kindergartens, hospitals, ports and other city institutions.

Advantages

Devices can be purchased ready-made or made independently. Having purchased a wind generator, all that remains is to install it. All adjustments and alignments have already been completed, tests have been carried out under various climatic conditions.

Neodymium magnets, which are used instead of a gearbox and bearings, allow you to achieve the following results:

• friction is reduced and the service life of all parts is increased;
• vibration and noise of the device during operation disappears;
• the cost decreases;
• energy is saved;
• There is no need to regularly service the device.

A wind generator can be purchased with a built-in inverter that charges the battery, as well as a controller.

Most common models

The generator with neodymium magnets can be manufactured with a single or double mount. In addition to the main neodymium magnets, the design may include additional ferrite magnets. The height of the wing varies, usually from one to three meters.

More powerful models have double fastening. They also have additional ferrite magnet generators installed and have different wing heights and diameters.

Homemade designs

Considering that not everyone can afford to buy a generator with neodymium magnets powered by wind, they often decide to build the structure with their own hands. Let's look at various options for devices that you can easily make yourself.

DIY wind generator

A wind turbine with a vertical axis of rotation usually has three to six blades. The design includes a stator, blades (stationary and rotating) and a rotor. Wind affects the blades and the entry and exit of the turbine. Car hubs are sometimes used as a support. This neodymium magnet generator is silent and remains stable even in strong winds. He doesn't need a tall mast. Movement begins even in very light winds.

What could be the design of a stationary generator?

It is known that electromotive force through a wire is generated by changing the magnetic field. In the core of a stationary generator, the magnetic flux is created by electronic control, not mechanically.

The generator controls the flow automatically, acting resonantly and consuming very little power. Its oscillations deflect the magnetic fluxes of iron or ferrite cores to the sides. The higher the oscillation frequency, the stronger the generator power.

Starting is realized by a short-term pulse to the generator.

Homemade generators with neodymium magnets are basically the same type in terms of their operating principle. The standard option is the axial type.

It is based on a car hub with brake discs. Such a base will become reliable and powerful.

When deciding to use it, the hub should be completely disassembled and checked to see if there is enough lubrication, and if necessary, clean off the rust. Then the finished device will be pleasant to paint, and it will take on a “homey”, well-groomed appearance.

Magnets are glued to the rotor discs. The author of the design presented in the photo in the article took twenty pieces measuring 25*8 millimeters. A different number of poles can be used.

In a single-phase device, the number of poles must be equal to the number of magnets. In three-phase, the ratio of two to three or four to three must be observed. Magnets are placed with alternating poles. They must be precisely located. To do this, you can draw a template on paper, cut it out and accurately transfer it to the disk.

To avoid mixing up the poles, make notes with a marker. To do this, magnets are brought on one side: the one that attracts is designated with a “+” sign, and the one that repels is marked with a “-”. Magnets must attract, that is, those located opposite each other must have different poles.

Usually superglue or something similar is used, and after sticking it is filled with more epoxy resin to increase strength, after making “borders” so that it does not leak out.

Three or single phase

A generator using neodymium magnets is usually made three-phase. A single-phase design will operate with vibration under load, since constant current output will not be ensured, which will result in an abrupt amplitude.

But with a three-phase system, constant power is guaranteed at all times thanks to phase compensation. Therefore, there will be no vibration or buzzing. And the operating efficiency will be fifty percent higher than with one phase.

Winding the coil and the rest of the assembly

Calculation of a generator using neodymium magnets is mainly done by eye. But it is better, of course, to achieve accuracy.

For example, for a low-speed device, where battery charging would begin to function at 100-150 rpm, from 1000 to 1200 turns will be required. The total quantity is divided by the number of coils. How many turns will be required in each of them.

The coils are wound with the thickest possible wire, since with less resistance the current will be greater (with a high voltage the resistance will take up all the current).

Usually they use round ones, but it is better to wind elongated coils. The inner hole must be equal to or larger than the diameter of the magnet. In addition, the optimal magnet will be in the form of a rectangle rather than a puck, since in the former the magnetic field is stretched along its length, while in the latter it is concentrated in the center.

The thickness of the stator is made equal to the thickness of the magnets. You can use plywood for the form. Fiberglass is placed on its bottom and on top of the coils for strength. The coils are connected to each other, and each phase is brought out to be connected then with a triangle or star.

All that remains is to make a mast and a reliable foundation.

Of course, this is not a perpetual motion machine based on neodymium magnets. However, savings when using a wind generator will be ensured.

Types of neodymium magnets

Neodymium magnets continue to be actively used in everyday life. And it’s not always harmless and legal. But this does not prevent us from increasing the level of production of these items on the territory of the Russian Federation.

The 50x30 magnet is a bestseller. It's small. For this reason, it can be used everywhere in domestic conditions. Do not forget that neodymium magnets do not demagnetize over time. So, the price of a neodymium magnet is more than affordable.

Positive aspects of using neodymium magnets

As mentioned above, today magnets are produced in a wide variety of configurations. They can be small, like coins, or huge - larger than a hockey puck.

Below is a list of the positive aspects of their use:

• affordable price;
• shelf life - eternity;
• convenient design (simple shapes);
• using a magnet, you can avoid using various temporary adhesives, thread seams, etc.

For example, there is a need to ensure that the curtains hold a certain configuration. To avoid removing or hemming them, you can use small neodymium magnets.

Or, for example, my son bought trousers, but they need to be hemmed because they drag on the floor. Again, you just need to turn up the trousers and secure the hem with neodymium magnets.

Where to buy neodymium magnets?

Today there are a huge number of scammers. The fact is that the average person will not be able to distinguish between a neodymium magnet and an ordinary, metal one, which will demagnetize after 3 months.

For this reason, it is strongly recommended to purchase neodymium magnets exclusively from suppliers who have proven themselves in the market only from the best side.

By and large, today the price of a neodymium magnet does not mean anything. Neodymium magnets, the prices for which are set by the seller himself, upon first request must provide documents confirming that he is actually engaged in the sale of neodymium magnets.

In conclusion, it should be noted that neodymium magnets can even be used to assemble a perpetual motion machine. Of course, it will be very small, but it can be used as a fan, etc.

Areas of application of neodymium magnets

29.03.2017

At this point in time, neodymium magnets are used in a wide variety of areas of industry and everyday life, namely: mineral processing, the creation of various magnetic equipment, mechanical and instrument engineering, as well as the manufacture of various equipment and electronics. Therefore, it is not surprising that every year an increasing number of people and companies are interested in where to buy high-quality neodymium magnets at a relatively low price.

Let’s give the correct answer to this in advance: in the MAGNIT STANDARD company, which has been creating and selling magnetic products in Russia for several years now. Today it is one of the leaders in this market.

Here you can buy magnetic mounts, magnetic separators, ferrite magnets, magnetic vinyl, neodymium magnets, acrylic keychains and many other similar items. More information about this organization can be found on its official website http://www.

magnitstandart.ru in the appropriate section.

As for the neodymium magnet, it is naturally much more useful to use than standard ferrite magnets. First of all, we note that these products can be small in size, but at the same time have a significant magnetic attraction force.

Applications of neodymium magnets in industrial fields

Most often, the above magnets find their application in industry, namely:

• These products are often used to create magnetic ionization and separators of impurities containing iron, as well as to magnetize individual components and elements. Quite often they are used in electronics, making sensors, computer hard drives, relays, video systems and telephones. These magnets are installed in filters that catch metal shavings and internal combustion engines.
• Manufacturers use neodymium magnets to produce electric motors and generators. Often the power of these magnets has a direct impact on the performance of these systems.

Use of neodymium magnets in medical and space fields

If we talk about medicine, these magnets are often used to create various medical equipment and conduct magnetic therapy, which helps eliminate pain during diseases such as arthritis. Quite often these materials are called “healing magnets.” In space, they help maintain muscle tone of astronauts.

What is a neodymium magnet?

Neodymium is the most powerful permanent magnetic material currently known to scientists. It's also very affordable, making it suitable for a variety of uses.

Rare earth magnets

The chemical composition of a neodymium magnet: Nd2Fe14B, in other words, two neodymium atoms, 14 iron atoms, and one boron atom. Therefore, such magnets are sometimes called “neodymium-iron-boron”.

These are rare earth magnets which, unlike conventional ferrite and ceramic magnets, contain atoms from the lanthanides or actinides of the periodic table. Magnets made from neodymium are the most powerful rare earth magnets.

Their strength is often given in Gauss (MegaGauss-Oersted, magnetic energy), and depending on the form and class can reach 13,500 Gauss or more, although 2,000 Gauss is common. For comparison, refrigerator magnets produce approximately 50 Gauss.

Advantages of neodymium magnets

The main advantage of neodymium magnets is their strength : for example, a magnet the size of a 5-ruble coin (25 mm in diameter and 5 mm in thickness) can withstand a weight of almost 9 kg! Two magnets connected to each other at the wrong angle can injure the skin to the point of bruising. Large magnets (for example, 50*30 mm) are extremely dangerous, so precautions must be taken when working with them. But if precautions are taken, neodymium magnets can be used in entertainment and even educational projects.

The second, but no less important, advantage of neodymium magnets is their service life . And although the technology for producing neodymium magnets is only 30 years old, we can already say that neodymium magnets lose only about 1% of their magnetic energy over 100 years! For comparison, ordinary ferrite magnets last no more than 10 years, after which they become just a piece of iron.

 
Have you ever wondered why ferrite magnets are most often made in the shape of a horseshoe, with one leg painted red and the other blue? The answer is simple: manufacturers tried to short-circuit the magnetic field lines of ferrite magnets to increase their lifespan. Neodymium magnets do not require this, so they can be made into almost any shape, and can also be made “multipolar”, i.e.

having several poles on the surface.

Magnetic phenomena

In our online store you can find film for visualizing magnetic field lines in a physical environment. Carefully placed neodymium magnets can promote diamagnetic levitation, a peculiar phenomenon that can lift small objects into the air without making contact with it.

If you try to drag a magnet across a non-magnetic surface (aluminum, copper), you will feel the force of “magnetic disturbance” or simply the resistance of eddy currents that arise when the magnet moves over a non-magnetic surface.

Try to repeat these experiments with our magnets, and you will not regret it!

It’s not for nothing that they say that magnetism is the most beautiful phenomenon of physics that we ever encounter!

How does a neodymium magnet differ from a regular magnet?

Today you can find a large number of different magnets on the Internet. They sell both toys and magnets, which can be successfully used in everyday life. In particular, many are not aware of the differences between ordinary and neodymium magnets.

In this article we will analyze in detail the advantages of neodymium magnets and the possibility of using them in everyday life.

Positive aspects of using neodymium magnets

Perhaps the main advantage of neodymium magnets is that it does not demagnetize over time. The magnetic field strength decreases by an insignificant amount after 50 years.

This means that even though a neodymium magnet is slightly more expensive than its regular counterpart, in the long run the purchase will be cheaper as it will last much longer.

Various methods of using neodymium magnets in everyday life:

• as toys;
• as decorations;
• in the kitchen for attaching knives to the wall, etc.

Neodymium magnets come in a wide variety of sizes and configurations. For example, on a balcony you can place a small magnet on the wall and on the blinds, which will securely fix the blinds.

After all, when it sways from a draft, it interferes, especially if you need to fall asleep.

In other words, neodymium magnets are absolutely safe and can be used wherever their properties are required.

Perpetual motion machine made of neodymium magnets

You can assemble a perpetual motion machine as a toy. It consists of a copper winding, photocells and several neodymium magnets. As a result, the role of the stator in a miniature electric machine is played by a neodymium magnet.

The rotor rotates as long as light hits it, that is, in the dead of night it stops, but at the first rays of the sun it is activated automatically. Of course, energy production is hardly possible.

But a fan can be mounted on the shaft of such a “perpetual motion machine”, which will circulate air, for example, for indoor plants located on the windowsill.

Dmitry Korzhevsky will demonstrate a “perpetual motion machine” that he assembled himself. As far as you can see, just a few neodymium magnets are enough to make the rotor of an electric motor levitate in the air:

Neodymium magnets, application of neodymium alloy magnets

Neodymium magnets are products made from an alloy of iron, boron and the rare earth metal neodymium.

It is thanks to the presence of the latter that such products have unique magnetic properties - incredible magnetic field strength (a small neodymium magnet can hold a weight of up to 800 kg) and a surprisingly long demagnetization time (up to 10 years).

It is difficult even to simply list all the cases where people use neodymium magnets to solve various problems; they have found application in everyday life, in technology, and in medicine. Here are just some examples of the use of neodymium magnets.

The use of neodymium magnets when working with equipment

For motorists, neodymium magnets are difficult to replace products. With their help, you can attach anything to the hood or bumper of a car without much difficulty, and there is a guarantee that the “magnetized” object will not be blown away by the wind during a fast drive. Motorists use neodymium magnets to clean various technical fluids (for example, car oil) from small metal particles.

You can also magnetize a simple screwdriver with a neodymium alloy magnet to make it more convenient to use. The use of neodymium magnets is very popular for removing information from the hard drives of faulty computers or other similar media (for example, CDs) when it is decided to get rid of it.

Of course, these are not all the cases and possibilities for using neodymium magnets that exist today.

In addition, the scope of their use is constantly expanding.

Areas of use of neodymium magnets

Neodymium magnets are simply a technological breakthrough. They are distinguished by very strong magnetic properties and a long demagnetization time. Namely, over 10 years a magnet loses a maximum of 2% of its strength. It is also worth noting that the price of them is very small compared to the benefits.

Due to their excellent properties, these magnets have quite a wide range of applications, both in technology and not very traditionally.

Here is a short list of industries:

• Household use
• Generators
• Car oil cleaning

Household use

Russian people have always been famous for their ingenuity. No one puts their minds to the topic of “free profit” like you and me. Therefore, such a technological tool as a neodymium magnet has found application in the service of ordinary people. Thanks to this magnet, you can easily stop any mechanical counter.

You just need to match the type of magnet to the type of meter and that’s it, the job is done. The technology is also very simple, you apply a magnet to the back wall of the counter and after 2 seconds you watch it stop completely. You can choose the right magnet and get advice on the website http://ostanovi-schetchik.ru/.

And also a little advice. If you are afraid that the craftsmen from the Housing Office will come and start pouring metal shavings onto the meter, then of course they will issue a fine. But all you need is a demagnetization loop, it can be bought on the market and is very cheap and a 220 volt outlet. Just wrap the meter, plug the loop into the socket, wait 5 seconds and that’s it, the meter is demagnetized.

Generators

A generator is a device that converts mechanical energy into electricity. If we consider the simplest generator, it will be a copper frame that rotates in a magnetic field, with different poles. All generators are built on the same principle. Therefore, the power of the generator directly depends on the power of the magnets. And it’s not difficult to guess that neodymium magnets are best suited in this case.

Cleaning oil in a car

Every motorist knows perfectly well that oil in a car is necessary in order to reduce wear and tear on parts due to friction. But over time, the oil itself becomes saturated with very small pieces of metal, and bypasses oil filters without problems. And if you don’t change the oil for a long time, then the wear of parts, on the contrary, increases. Therefore, it is necessary to periodically change the oil.

But trucks need a lot of this oil, and replacement always costs a decent amount. But with the help of neodymium magnets, it is completely cleaned. If you attach a magnet to the crankcase box, then all the parts will immediately stick to this place, after which they can be removed without any problems. And this will add several thousand more kilometers without changing the oil.

Application of neodymium magnets

Today, almost everyone has heard that there is such a type of magnets as neodymium. But, unfortunately, few people know the scope of their application and purpose. It is worth noting that the modern market offers a wide range of products. You can choose the size of the magnet and some of its technical characteristics.

It is important to contact specialized stores to purchase quality products. If you are looking for high quality neodymium magnets, then http://neodimovie-magniti.ru/ can help you. We offer a wide range of products at the best prices.

Let's consider the main scope of application of neodymium magnets and their features.

Cleaning engine and transmission oil

Oil is used for different parts of cars and other parts of machinery that come into contact with each other. It allows the parts not to wear out and allows them to perform at their best.

Oil deterioration occurs due to the fact that small metal parts get in during the operation of the mechanism. Very often filters cannot cope with such contaminants, so it is necessary to use a neodymium magnet.

It allows you to “bring out” these elements to an area that is easy to clean. For this purpose, neodymium magnet is used very often.

Search for various items

A neodymium magnet is also considered very convenient for searching for various metal objects in bulk materials on the floor. For example, if nails or screws are lost in the sand or on the floor, then the device will help you find them. Very often they also create a ring magnet, in which case searching for objects will be much easier.

Cleaning an aquarium using a neodymium magnet

Quite an unusual use of this element, but very practical. If you have a large aquarium and you don’t want to wash the inside of it with your hands, you can use a neodymium magnet. This is very simple to do: you need to take one magnet, attach a sponge to it, and move another magnet on the other side of the aquarium (from the outside). This will help press the magnet inside onto the glass so you can drive it outside.

There are also other uses for neodymium magnets. With their help, you can stop the operation of the counter, destroy various video and audio information on magnetic media, and you can repair some musical instruments that are deformed and have very thin walls.

Original ways to use neodymium magnets

articles:

Humanity has been familiar with such an irreplaceable and multifunctional invention as neodymium magnets for several centuries. Some people purchase them for the purpose of attaching them to meters in order to slightly reduce their speed and thereby reduce utility bills. Others use them for repairs, but few know that neodymium magnets can be used for many other purposes due to their excellent property of attracting metal.

Application in technological processes

At home, neodymium magnets can be used in various fields. One of the usual methods of application is search. If you move a magnetic ball over the surface, various metal objects will be attracted to it. If you tie it to a long thread, then such finds can be found even in the walls.

Therefore, such a magnet is indispensable for finding lost bolts, screws and various jewelry that contains metal in the alloy. Surprisingly, using a magnet you can repair musical instruments made of a thin layer of metal. For example, if a dent appears on a saxophone, flute or trumpet, it can be easily repaired.

From the outside of the tool, you need to move a magnet over it, and place a metal ball or other round object of the desired size inside. The magnet will attract it and put pressure on the walls of the object. Many people have long forgotten about such devices as magnetic recording discs and films.

However, some do not want what is recorded on these outdated means of information transmission to reach strangers. To remove information from such media, it is enough to treat it with a strong magnetic field. This will ensure that everything written to them is permanently deleted.

Many car enthusiasts know that the rubbing parts of engines, motors and other devices can wear out due to low-quality oil, which contains many foreign impurities. You can clean transmission and engine oil using a neodymium magnet, which will capture even the smallest particles of impurities.

Hobby and entertainment applications

There are a huge number of areas of life that are difficult to imagine without using the benefits of neodymium magnets:

• Games and entertainment. Various puzzles and puzzles based on magnets perfectly develop a child’s thinking and can capture his attention for a long time. That is why they are actively used in the manufacture of toys and advertising products.
• Tricks. Most magician tricks are based on hanging various objects in the air. This cannot be done without using magnets with a powerful field. However, such large neodymium magnets should be handled very carefully, as if damaged they can cause poisoning to the body.
• Breeding aquarium fish. It is known that these pets require special care: they must have clean, oxygenated water and a clean aquarium. Any water blooms over time, as various microorganisms live in it. If the aquarium is huge, cleaning it is quite difficult. If you lower a magnet with a sponge attached to it into the aquarium, and on the other side attract it with another magnet, you can quickly clean the glass without even getting your hands wet.

The profitable neodymium magnet is widely used in Moscow and all over the world. It can be used for various purposes, all you need is an extraordinary approach to the processes.

Neodymium magnets in everyday life

    Neodymium magnets are considered the best clamps and fasteners. Thanks to the power of the magnetic field, they are able to play the role of a vice. In everyday life, there is often a need to glue various materials or parts together. It is enough to place them between a pair of neodymium magnets, and extremely strong fixation will be ensured. It is also important that the force exerted by the magnet does not decrease over time, therefore the stability of the fixation is ensured.

     Another advantage of neodymium magnets lies in their compact size, so they can be used for gluing parts and materials with complex configurations. Such magnets are also indispensable for fastening any metal objects. For example, you can place various devices on the walls of the kitchen, fixing them with magnets. By the way, with the help of powerful neodymium magnets, you can even hang a bicycle in the garage, not to mention tools.

   The easiest way to find a lost metal object (a nail, keys or a needle) is to attach a magnet to some handy object and move it under furniture or along the floor for a while. During repairs, the location of the reinforcement in the walls can be determined in the same way.

   Neodymium magnets can easily find objects made of any metal in soil and sand, so they can be used in searching for various products in nature. By the way, it was from this activity that many collectors of rarities began to get involved in treasure hunting.

    Summer residents have the opportunity to use a magnet to retrieve objects that have fallen into a well, water tank or pond. For a similar purpose, neodymium magnets are used to lift metal objects from the bottom of rivers or lakes.

    Today, every home has a computer, and the user has information recorded on a hard drive, CD, etc. If a hard drive or mobile storage device is broken, this does not mean that someone will not be able to read information from it. Therefore, before throwing away disks, treat them with a neodymium magnet, and the data will be guaranteed to be destroyed.

Another common application is the use of neodymium magnets for recreational purposes such as performing magic tricks, assembling models, and solving puzzles. In this area, the possibilities of such magnets are almost limitless.

You can attach them to two objects and perform a trick of attracting them to each other. There are few people who are not attracted to the popular neocube puzzle. This toy consists of many magnetic balls of the same size.

The stability of the design and the ability to assemble standard and original figures from the neocube are due to the magnetic field of the neodymium magnet.

Use of neodymium magnets by motorists

    Car enthusiasts today use neodymium magnets to clean oil, in which metal particles accumulate due to friction of engine parts. A magnet can be used to “catch” such particles and concentrate them in places where they can be most easily removed. For example, you can attach a high-temperature magnet to the oil pan drain plug and clean it of stuck particles as needed.

    A neodymium magnet is perfect for attaching various signs and signs to the roof, hood or trunk of a car, which will not move even during high-speed traffic or strong winds. Neodymium magnets can also be used to attach any devices in the cabin. In addition, magnets can magnetize tools (for example, a screwdriver) and restore the lost characteristics of other magnets.

Application in industry and other fields

The use of neodymium magnets in industry is due to the unique properties already described above.

In the production of units and parts, these products perform the function of a vice or clamps, but they also make it possible to sort metal objects and lift fairly heavy devices and products to a considerable height.

Such supermagnets are used in the manufacture of sensors and relays, in the production of electric generators, wind turbines and hydroelectric power stations, as well as diagnostic and medical equipment.

In the agriculture and food sectors, magnets are used to remove foreign metal objects from bags of cereals , grains and other products.

In workshops and workshops where large amounts of iron shavings are generated, neodymium magnets allow you to avoid injuries and easily solve the cleaning problem. For this purpose, a magnet is placed in a bag and brought to the place where metal shavings accumulate. The shavings stick to the magnet, and when the bag is turned inside out, they remain inside.

Powerful magnets are also used in the construction industry for fastening formwork, in the manufacture of cabinet furniture, jewelry and jewelry. Applications for neodymium magnets include, but are not limited to, modern medicine and the health industry.

Finally, magnetized water has a beneficial effect on the human body, and the force field generated by the magnet can normalize blood pressure and alleviate the symptoms of arthritis.

Application areas of magnets

— Advertising and souvenir products (magnets for folders, toys, jewelry, refrigerators, mounts for advertising posters, banners, posters, gift wrapping, etc.);

— Textile products (fasteners for bags, cosmetic bags, clothes, phone cases, etc.);

Using neodymium magnets at home

A neodymium magnet practically does not lose its properties over decades. In a home environment, these products can be used usefully and even for entertainment.

In everyday life, neodymium magnets can be used for the following purposes:

1. suspension of operation of gas and water electricity meters - a neodymium magnet disables the electromagnetic field of the meter;
2. cleaning aquariums - attach one magnet to a sponge and lower it into the tank, and control the other from the outside by making the necessary movements;
3. interesting board games with children - you can attach one magnet to the toy and move the second one under the table, due to which the upper object will move;
4. searching for metal objects and artifacts in bodies of water using a special magnet with a hook - search magnet;
5. destruction of video and audio from magnetic media - just bring a magnet to the source of information and it will be erased.

Neodymium magnets are used not only at home, because their power can achieve certain benefits in many areas.

Neodymium magnets - where else can they be used?

Mankind has come up with a lot of useful things, and often their components are neodymium magnets. Their use in the home sphere is quite common, but they are more actively used in the following areas:

1. production of audio and video equipment;
2. production of disks;
3. cleaning car parts from engine oil;
4. production of toys and puzzles;
5. treatment of physical diseases and nervous disorders using magnetic massage;
6. production of lifting equipment - magnets are attached to cranes.

It can be noted that there are a lot of areas in which neodymium magnets are used. The rare earth metal alloy neodymium is found in almost all areas of our lives. It is always good to have a neodymium magnet at home, because it will not only help you play with your child or find metal objects, but will also be useful for people who have marine life or cars at home. A neodymium magnet is present in almost every area of ​​human life.

Neodymium magnets. Application. • DIY crafts

Most likely everyone has already heard about neodymium magnets. Such magnets are made from an alloy of rare earth elements (neodymium, boron and iron (Nd2Fe14B)), which has excellent magnetic properties. It is not difficult to purchase them now, so we will tell you about the benefits of using them on the farm.

The main ways to use neodymium magnets:

1) Used in various toys and puzzles. This uses small and weak magnets, usually in the shape of balls or squares. These magnets are assembled into different shapes and designs. But the main thing is not to forget that these magnets CANNOT be given to small children!

2) Neodymium magnets can be used as clamps (vices). To do this, you will need two medium-sized magnets. You can fix a pair of soldering wires or a board, you can also press glued flat parts on both sides, etc.

3) Motorists can use neodymium magnets as an additional oil filter. If you attach it to the engine crankcase drain plug, it will trap all metal particles in this place, which can then simply be removed.

4) Due to their attractive force, magnets can be used in search activities. For example, if you need to find a fallen needle on a carpet or catch various metal products in a river (lake) (they even sell special search magnets with a ready-made hole for attaching a rope).

5) Using a neodymium magnet, you can magnetize various steel tools (bits, screwdrivers, tweezers, etc.). Also restore the properties of an ordinary magnet that has become demagnetized.

6) Using a powerful magnetic field, you can delete data from magnetic media (hard drives, audio and video cassettes, credit cards, etc.).

Conclusion:

Everyone will find benefits for themselves from using neodymium magnets in their household. Just be sure to remember that when working with magnets (especially powerful ones), you need to follow safety precautions. If a finger or other part of the body gets between the magnets at the moment of connection, this can lead to bad consequences. Take care of yourself!

Neodymium magnets - real application in technology

16.04.2016 15:09

Anyone who has ever visited, and has already heard about neodymium magnets. All social networks are simply teeming with various videos on the use of neodymium magnets in everyday life, their use in various experiments and experiments. Indeed, it is useful to have several neodymium magnets at home for various purposes. Moreover, the price of small copies on www.magnitu.com.ua is practically insignificant. And such magnets can bring much more benefits in the future than money.

But are all these magnets created just to collect screws around the apartment or hang keys on a switch? Of course not. And now we will consider the most promising applications of neodymium magnets in technology.

Increasing the power of DC motors

The bottom line is that when creating DC motors, they are faced with one single problem - to make a motor that will be as compact as possible. But as a rule, the limitations come down to the fact that the strength of ordinary magnets is not enough.

And by replacing conventional magnets with neodymium ones in any DC motor, we get an increase in the latter’s power by 1.5 and sometimes 2 times.

This phenomenon is often encountered by aircraft modellers when they need to get maximum performance with minimum weight.

Magnetic bearings

It has not yet been possible to completely create a non-contact bearing, but it is already possible to reduce the friction force of a flywheel enclosed in 2 pairs of magnets. And prototypes show that in the future it is possible to collect a large potential of kinetic energy and store it for quite a long time. And leave the axial stabilization of the flywheel on the metal axis. How such a flywheel works is shown in more detail in the figure.

Magnetic buttons

Since any magnet is a conductor of electric current, by placing two magnets with like poles facing each other, we get the simplest button without locking.

And since any button is limited by the stiffness of the spring and becomes unusable after a certain number of clicks (everyone is familiar with the operation of the left mouse button after one or two years of operation), then in the case of a magnetic button we will get a functional button for 10-15 years.

It is worth saying that most likely everything else in this mechanism will become unusable and only then the button. And such buttons have already proven themselves in mechanical mods of electronic cigarettes.
