How to make a magnet for gold

A powerful neodymium magnet will check the authenticity of gold and silver - World of Magnets blog

Despite the fact that each product made of precious metals is given a sample, which should confirm its authenticity, doubts can still arise. The development of modern technologies makes it possible to easily counterfeit precious metals.

Moreover, the appearance of such fakes is completely identical to the original and visually it is almost impossible to determine whether the jewelry is made of gold or silver, for example, or whether base metals were used for its manufacture.

Of course, you can consult a jeweler, but you need to pay for it.

Are there ways to check the authenticity of gold or silver at home? If you purchase a powerful neodymium magnet, then it is quite possible to establish the authenticity of the product with a high degree of probability.

Counterfeiting of precious metals is one of the most ancient types of fraud.

What properties do gold and silver have?

The concept of “noble metals” is applied to the platinum group metals, which include gold and silver. This name was not given by chance. It reflects the properties of these metals not to react to the influence of most non-metallic elements. In other words, unlike base metals such as copper, iron, etc.

, gold and silver alloys do not oxidize and do not change their appearance under the influence of oxygen. The same can be said for exposure to water, as well as many other elements that can lead to rapid corrosion and oxidation.

Well, don’t forget about the beautiful appearance of these materials, which is why they are primarily in demand in jewelry.

Gold and silver alloys do not oxidize, do not change their appearance under the influence of oxygen and do not react to a magnetic field

However, for authentication purposes, another property of the metals in this group is important. They do not respond to the influence of a magnetic field. That is, even if you purchase a powerful neodymium magnetic disk and bring it to the jewelry, they will not react at all. It is this quality that can be used for verification. First of all, you need to decide which materials are capable of creating a powerful specific field. Most often, this list includes only four types of substances. The first two, alnico and samarium-cobalt, are used quite rarely for objective reasons. If you are going to test gold and silver, then you need to purchase either ferrite or a powerful neodymium magnet. The latter are often used to search for iron-containing products, so you can often find search magnets on sale that have a specific shape. This option is also supported by the low cost of such devices.

Is gold attracted to a magnet? Be careful, it's not gold!

The check is very simple. It is necessary to bring the neodymium plate, which has a strong attractive force, to the product. If the jewelry is made of gold or silver, then, as already indicated, it will not respond to the created field. What if it did react? In such a situation, two conclusions can be drawn:

• • either it is a fake;  
• • either the alloy contains many impurities and the jewelry is of low quality.

Search magnet for gold and silver: operating principle

A search magnet for gold and silver is designed to detect products and their fragments. Many coins made from pure metal contain ligature components that create the magnetic field necessary for searching.

• 1 Action of a magnet
• 2 Search devices
• 3 Safety precautions

Action of a magnet

A search magnet allows you to detect coins made from precious metal alloys. It is known that noble metals do not attract each other; they belong to the class of diamagnetic materials.

In science, there is a known case of creating an artificial field, in which magnetic properties were given to gold and silver atoms by chemical means. The researchers claimed to have used a controlled chemical reaction to create compounds of noble metal nanoparticles that act as permanent strong magnets.

Under natural conditions, pure gold does not react to a search magnet; materials containing ferromagnets fall into the interaction field. Their distinctive feature is the ability to be magnetized and maintain a field.

Magnetic and attracted:

• copper;
• brass;
• gold;
• silver;
• tin;
• precious stones (turquoise).

The search for gold and silver in their pure form becomes more difficult, since these metals do not react to the device. The ligature additive included in the jewelry helps to detect jewelry.

A product made of a noble alloy has a sample indicating the content of pure precious metal. Rings, chains, and bracelets are made from popular jewelry material corresponding to 14 carats. Products often contain nickel as an alloy, which reacts to a magnet.

Search devices

To detect materials on the surface and bottom of reservoirs, a magnet is used to search for gold. Existing device models allow you to expand or limit the search area.

For example, a cubic zirconia ring can be found using a one-way device. To ensure that the product does not corrode over time and can magnetize objects, manufacturers began to cover search devices with a layer of polymer materials, aluminum, and zinc.

The force of the device is measured in gauss. To determine the approximate power indicator, a steel plate and a dynamometer are used. When several magnets are combined, the field effect increases by 30%. A correct device has equal force concentrated at its poles.

The most powerful search device is considered to be a neodymium magnet, which has limitations in its properties. Using the device at temperatures exceeding 80°C will result in loss of performance.

Before you buy a device, you need to think about the purpose for which the purchase is being made. The price of a magnet is much higher than the cost of a finished jewelry alloy product. Therefore, before purchasing a device, you need to evaluate the profitability of searching for scrap metal.

You should not look for a magnet specifically to detect precious metals, because with this approach you can be disappointed in an exciting activity without experiencing a sense of adventurism. After all, with a targeted approach to treasure hunting, there is a possibility of finding a treasure with gold and silver items placed in a metal box.

Nowadays, there are many items of antique value that can be found using a magnet.

Security measures

To lift magnetic field-responsive materials from the river bottom, search devices are used, the strength of which depends on the neodymium content. It is important to consider that flat objects are attracted better than round ones.

When working with the device, you need to take into account the interaction of the magnetic field with electrical appliances, watches, and plastic cards. It is recommended to store the magnet in a plastic container that limits the action of the device.

You must not be in the magnetic field created between a metal object and the device to avoid a fracture or bruise. After each use, the device is cleaned of dirt, wiped and placed in a case. These procedures will extend the service life.

Are there search magnets for gold, silver, copper? (answer: NO)

Only steels have magnetic properties , and not all of them. For example, austenitic stainless steels do not attract magnets because they do not have ferromagnetic properties. However, there are a sufficient number of enthusiasts who believe that magnetic waves are emitted by any metal, and therefore there should be a search magnet for gold and silver, and for some this expression is quite normal for perception and practical use.

ATTENTION! MAGNETS FOR SEARCHING GOLD, COPPER, SILVER DO NOT EXIST!

THEY SIMPLY ARE NOT - ANYWHERE!

In our article we describe the theory of how non-ferrous and precious metals can be detected using magnetic fields. This article is our fantasy, supported by scientific developments of foreign scientists.

See also the article - Extraction of scrap metal from water (about ferrous metal and search magnet).

Device for adjusting the magnetic field from metal objects

Strictly speaking, this is not a magnet, but rather an electromagnet, with the help of which you can initiate and configure any magnetic radiation, even quite weak ones, to be captured by appropriate devices. It is not easy to build such a device, but the authors, citizens of Australia, have no doubt about its effectiveness.

That's why they patented their invention in their patent office. Based on the fact that Australian soil is not much different from domestic soil, we will give a description of the device and operating principle of such a magnet for gold and silver.

Although it is necessary to repeat - in the generally accepted sense, this design has nothing .

The operation of the device is based on the well-known physical fact that when any object that generates magnetic oscillations in an alternating electric field moves, changes occur inside the trapper circuit associated with the movement of atoms around the nucleus.

If the area of ​​electric field generation is sequentially moved along or across the magnetic field from a metal object, changes will occur in this area, the intensity of which determines the degree and strength of the interaction of two fields - magnetic and electric.

The difficulty is that strong magnetic fields are not created by noble metals . It is known, for example, that, according to the principle of decreasing, the electrochemical potentials of non-ferrous metals are located as follows (we consider only the area of ​​interest to us): copper → mercury → silver → palladium → platinum → gold.

Thus, if the expression “is copper attracted to a magnet” may still have some basis, then the phrase “magnet for gold” does not make any sense at all.

It is more correct to talk about an electromagnetic trap, which will record the fact of a coordinated change in electric and magnetic fields in a certain, rather local, metallic volume.

how copper interacts with a magnet:

Recording of changes that occur in the apparatus under the influence of such fields is captured by the measuring circuit. It is a highly sensitive spring made of rhenium, a rare metal that is absolutely insensitive to temperature changes. The rhenium spring must be adjusted to operate.

  The process is to set the conditional zero of the device, for which it is placed as far as possible from all metal objects. In urban areas, such a “search magnet for gold, silver and other precious metals” will not work. However, search engines are much more likely to look for gold, platinum, copper, silver, etc.

in old abandoned rural estates

With any movement of the device, a similar action occurs with the electric field, while the magnetic field remains constant in coordinates. Therefore, the resulting movement of the spring will also be different.

Where it turns out to be most intense, its source is almost certainly located - the magnetic field. Another thing is that this kind of search magnet for non-ferrous metals will not be able to show which metal is hidden under the thickness of wood or earth.

But the device will definitely show that there is metal there.

Any metal can be detected by a magnetic field

The principle of operation of such a pseudo-magnet is similar to the coils of a metal detector, with the only difference being that the “magnet” will be tuned to only 1 metal and this is in theory - but we don’t know how it will behave in practice, BUT, most likely, it’s cheaper, faster and simpler will use an ordinary metal detector to search for non-ferrous metals, since not a single wizard has yet invented a magnet for non-ferrous and precious metals, maybe because there are no wizards!

How to assemble and set up

It will be very difficult to find/buy a rhenium spring, but all other parts of the device are quite accessible for making yourself. The sequence is:

1. A steel axle is made from a thin-walled steel pipe with a diameter of no more than 16 mm. Its length should not be less than three diameters, otherwise the change in the magnetic field cannot be detected.
2. A frame is made from thin copper or brass wire. The authors do not describe its dimensions, but, based on the dimensions of the tubular axis, it should be at least 200x200 mm. The frame must be sufficiently rigid.
3. Three (as many as possible) holes are drilled in the tubular axle at equal distances, in which the wooden axles are placed.
4. Thin-walled wooden disks are made, the number of which must correspond to the number of holes drilled in the axle. Obviously, discs can also be made of plywood: what matters is the mass of the disc and its absolute immunity to magnetic fields.
5. The central sectors of each disk are covered with metal foil made of the metal that will be searched. Thus, a search magnet for non-ferrous metals - copper, gold and silver (platinum is searched for much less frequently) should have three sets of replaceable wooden disks.
6. The frame with disks must be able to move freely along the entire tubular axis with fixation in a certain place. If the fits of the mating parts are made with the required accuracy, then there should be no swaying of the frame when it moves.
7. To create a magnetic trap, plates from an old transformer are used, which are packed into the frame outline. The distance between adjacent plates should not exceed 1.5 mm in thickness and 56 mm in length. Such plates form the screen of the device that perceives magnetic radiation.
8. Next, assemble the magnetic coil. You will need a solenoid made of 600 layers of enameled wire, which is connected to an alternating current voltage source. The winding should be multilayer, this will reduce the parasitic capacitance of the coil and make the device less inertial.
9. A ferromagnetic or - which is better - a ferroelectric core is inserted inside the coil.
10. By connecting this structure through a step-down transformer, a constant position of the frame with the plates is achieved relative to the wooden disks. This will be the conditional zero of the search “magnet” for non-ferrous metals.

The easiest way to check whether a search “magnet” attracts gold and silver is on a real object made of these metals. At the same time, it will be possible to establish the practical sensitivity of the device.

Magic rituals with a magnet

• Let's tell fortunes for free
• Fortune telling online
• Are you loved?
• True fortune telling

How to recharge a magnet?

A magnet is the most powerful tool in magical circles, but it, like all other magical amulets, requires recharging. It is carried out at least once a year - more often if possible.

During the ritual you feed your amulet. If you ignore this procedure, he will remain hungry and will not provide the assistance expected from him.

For the ritual, prepare iron filings. First, wash the mineral with water, then with alcohol and let it dry thoroughly. When this happens, sprinkle a handful of iron filings on top.

Let the magnet lie in peace and quiet for a while - do not touch it or make noise near it. Do not turn on the TV or computer.

When everything is finished, carefully collect the shavings. You can soak it in water and dry it to use it again a year later for the same purposes.

Place and storage conditions

It is important to preserve not only the quality of the mineral, but also its magical properties. According to the advice of professional magicians, two conditions must be met:

• When you are not using the talisman, always place it in the same place. This must be a special container that is made of non-magnetizable material. Otherwise, the magical power will gradually disappear. What are these boxes made of? These are wood, glass, plastic - materials available to everyone.

• And one more thing - use each of the amulets for one purpose. That is, you cannot include the same magnet in love rituals, and after a while in money rituals. You will not solve any of the existing problems. “Repurposing” magnets is impossible - this rule must be remembered.

Ritual to make wishes come true with a magnet

In the magical community, everyone knows the effective technique using magnets.

In order for your ritual to have the desired effect, prepare the following attributes:

• magic aromatic oil;

• church or regular candle (choose the color depending on the characteristics of the ceremony);

• a bowl made of fire-resistant material;

• a blank white sheet of paper;

• a picture depicting your dream.

For example, if you want a new apartment, choose a beautiful image of an apartment with a good renovation and a stylish interior.

If you want a brand new car, a picture with the best model will do. If you dream of meeting a specific person, get his photo.

It happens that it is impossible to express cherished thoughts with a drawing. In such a situation, describe them in words on the sheet.

Now fold the picture or paper into an envelope and write your name on the back - nine times.

Important reminder: the ritual is performed exclusively during the waxing moon .

On the wax surface of the candle, write a word that defines your goal (“car”, “house”, “family”). Please also include your name.

Try to direct all your thoughts to the magical procedure - concentrate on the positive result. Throw all other problems and matters into the background, or better yet, forget about them altogether for a while.

Apply your chosen oil to the candle and light the wick. Pray to the Lord, read Psalm 23. Mentally turn to all the Saints. Also express your dream in your own words and once again ask heaven for help and support.

Dip the folded sheet on four sides in oil and seal the envelope with it.

Wrap the paper clockwise with the words:

“With God's blessing, (the name of your goal) comes to me as easily as I folded this paper. Amen"

Now place the magic envelope on the prepared plate and cover it with a magnet on top. Again you will need oil - drop it on the magnet three times. And sprinkle the mineral with sand.

Repeat the sacred Psalm again. The ritual is almost complete. All you have to do is put out the candles.

Wait until the next morning to light the candles again and read the Psalm. Repeat this ritual until the waxing moon phase is completed.

And don’t forget to feed your amulet after the magical ritual. Do this using iron filings and the following spell:

“With God's blessing, I feed you, and you will feed me, so (the name of your goal) comes to me the way this sand is drawn to you. Amen"

Do not doubt the magical power of a magnet, and very soon your dream will come true. And after the result obtained, bury the magnet deep underground.

For your next wish you will need to create a new amulet.

Is gold magnetic - Metals and their processing

Treasures, treasures, hiding places, jewelry These words reek of adventure, adventurism, and romance.

Who didn't dream of finding treasures as a child?

Some adults have kept their childhood dreams and are making them come true by engaging in treasure hunting.

Like all passionate people, amateur search engines have their own clubs and communities. There they exchange experiences, discuss search devices, and make collective forays.

Modern devices for detecting metals help treasure hunters. One such device is a search magnet. More about it below.

Design and types

A search magnet is capable of finding, capturing and lifting metal objects whose weight is much greater than the device itself by 50-100 times. The device is otherwise called an eternal or powerful magnet.

The working fluid consists of a neodymium magnet (contains Nd-Fe-B) enclosed in a glass-shaped turned steel body.

The body is coated with zinc, and the body is coated with nickel, which allows to be used for searching in water .

The housing protects and shapes the magnetic field in the correct direction. There are:

1. Single-sided - convenient for searching from a boat, pier, bridge.
2. Double-sided - have a universal purpose.
3. Trawls are good for examining the bottom of reservoirs.
4. Rods – for narrow and hard-to-reach places for conventional magnets.

They also differ in body diameter and magnetic strength .

A special bolt (eye bolt) is screwed into the top or side, intended for a cable or rope.

The second function of the bolt is that it is used to remove an object from a magnet.

To do this, the eye bolt is screwed completely into the body, after which the magnetized object can be removed.

Search magnets are most afraid of high temperatures (above +80); when exposed to strong heat, they lose their functions .

It is easy to work with: having attached it to a rope or cable, it is simply lowered into the desired place.

Objects containing ferromagnetic metals will be attracted to the device. Together with a magnet, they can be removed to the surface.

The fundamental difference is that a metal detector can only indicate the location of an object, while a magnet allows you to immediately “get” it. However, a magnet will not help when searching in the ground . Therefore, these two devices in the seeker’s arsenal are designed to complement each other, but not replace each other.

Other distinctive features:

• the magnet retains its functions in an aqueous environment ;
• no need to buy batteries or accumulators ;
• absence of sound signals that attract attention or “declassify” the seeker;
• do not take up much space, easy to take with you;
• objects are attracted on their own ;
• affordable price;
• resistant to damage;
• long service life, provided that the operating rules are followed - they lose one percent of their strength in a hundred years .

Where can it be used?

Used to search for objects outside the field of view :

• in caves;
• mountain failures;
• wells;
• sewers;
• bodies of water;
• swamps.

A magnet will be a good help during archaeological excavations and searches for wartime items.

Usually used in tandem with a metal detector. Using a magnet, excess, unnecessary metal is collected, but which will be “distracted” when searching with a metal detector. The metal detector then searches for more valuable alloys such as gold and silver.

Objects that are made of metals that have ferromagnetic properties can be attracted by such a magnet. For example, cast iron or nickel.

Ferromagnetic properties are properties of base metals that allow them to “stick” to magnets with great force.

The burning question is, is it possible to lift objects made of precious metals using a magnet?

It is possible if the composition contains metals that react to magnetic attraction.

There is no special search magnet for gold and silver .

However, it is quite possible to obtain jewelry and coins made of precious alloys with its help, because they also contain other elements that the magnet will attract.

For example: 585 standard gold consists of 58.5 percent of gold. The remaining 41.5 percent comes from other metals, including nickel.

Nickel is easily attracted to a magnet. However, in order for such jewelry to be lifted, there must be a touch to the jewelry find.

It's the same story with silver. If the alloy has ligatures (metals added to jewelry to increase wear resistance), objects or jewelry will be attracted.

Review of popular devices and their prices

As in any serious matter, caution is important :

1. Ask the people you are going on search trips with to see if they have pacemakers . The device can disrupt the normal operation of the pacemaker.
2. Credit cards with a magnetic stripe, mechanical watches, hearing aids and telephones should be kept away from the magnetic device.

Easy to use and maintain, affordable, these devices can help with:

• searching for gold and other precious metals;
• when digging non-ferrous metal and ferrous metal.

There are practically no restrictions on the place of application. At the same time, they are durable and do not lose their properties.

If the operating rules are followed, search magnets will help in searches for a long time.
