Typically, powerful magnets are designed to find precious metals. A search magnet reacts to gold and silver quite strongly, and although it is difficult to find them in their pure form, its power is enough to pick up jewelry and coins from the ground. The main goal of all search engines is treasures, expensive coins, and sometimes just ferrous metal.
The article will describe the structure of the magnet and the basic principle of operation. He will also figure out what exactly can be found with its help and how to find expensive alloys. It will be explained in detail what ferromagnets, paramagnets and diamagnetic materials are. In addition, valuable tips and recommendations will be given that will greatly simplify the search for valuable items.
Search magnet device
This device consists of a steel case, inside of which there is a neodymium magnet. It is made from a rare alloy containing neodymium, iron and boron. This compound has a powerful attractive property. Despite its compactness, it is capable of holding things tens of times its own weight.
To make it easier to get various things, the case is equipped with a special mount. It is screwed into the magnet body via a thread. On top of the fastener there is a fastener in the form of a hook or loop that will hold the cable or rope. This mount has a rigid base that is firmly screwed into the body. The entire structure has a reliable foundation, and in this case, there is no fear in lifting any expensive and heavy thing.
Principle of operation
The search magnet has rather poor functionality. The main task of such an object is to attract as many metal objects as possible. But the device copes with its main task more than well. Thanks to its unique design, it has great strength and is able to hold quite large objects, as well as objects containing gold or silver, which ordinary magnets cannot handle.
This is especially convenient when getting things out of wells, funnels and various pits. It's also good to use this thing underwater. In water, all objects are subject to great resistance, and picking up any object becomes a rather labor-intensive task. But with a neodymium magnet, searching and removing such objects is greatly simplified.
What items can be found
When asked what kinds of things can be found using a search magnet, iron objects, including coins, immediately come to mind. Almost all paramagnetic metals can be found. Simply put, materials that are attracted to the magnet body, but more on that later. Such coins, or precious metals, can be of great value. For example, you can find iron coins from the period of Tsarist Russia, as well as many rare Soviet coins.
Powerful magnets can attract metals such as:
Most searches are carried out in attics, in various beaches and public places where people can lose things, as well as in wells and pits. In such places they usually find costume jewelry, expensive jewelry, various metal boxes, and sometimes even expensive mobile devices (on the beach). This is what finding things on land is all about.
As for water, you can also find many valuable things, including gold jewelry. Also, thanks to superstitions, a whole fortune of coins can be raised from the bottom. Moreover, there is no need to get coins from city fountains, since there are quite a lot of abandoned wells that no one needs, but they store precious things.
Draw with lapis pencil
A lapis pencil is needed to stop the bleeding. This is an antiseptic based on silver nitrate, it can be bought at a pharmacy, it costs about 100-150 rubles.
To check the authenticity of gold, soak the item in water. Then, using a lapis pencil, draw a small line over the wet one and wipe it off.
Lapis does not react with gold, but does react with other metals. If a trace remains, then the gold is fake or of very low standard. Nothing will happen to genuine metal.
Does a magnet attract gold and silver?
Is it possible to find pure gold or silver with powerful magnets? No, since such metals are diamagnetic, that is, they are not attracted to magnets. But it's not all bad, thanks to all the power of neodymium alloy, it is possible to get some jewelry. Such objects usually have a ligature in them.
This alloy helps precious metals such as gold or silver acquire certain properties. For example, silver jewelry does not darken as much, but gold jewelry is more durable. But the most important thing is that the ligature allows magnetization and makes it possible to find various alloys.
But it is also possible to find pure gold or silver. At the beginning of the article it was said that iron boxes can be found. Typically, jewelry made of gold or silver is stored in such cases. So, walking through an attic or similar places, you can get rich, in the literal sense of the word.
Is gold magnetic?
When we talk about pure gold, we mean 999 purity. This number means that there are 999 grams of pure gold per 1 kg of alloy.
The purity of such a metal does not allow it to be influenced by a magnetic field.
Gold has the following properties:
- Softness. Gold is easily amenable to physical influence. At room temperature, a person is able, without much effort, to change the shape of a gold item. For example, in films that describe the reign of monarchs, the coin was tested “by the tooth.” This is how people determined whether a coin was counterfeit.
- Plastic. Despite the fact that it bends, there are no defects left on it. While other metals may crack during physical manipulations.
- Inertia. This property suggests that as a chemical element, gold rarely interacts with other elements. Even with such a strong oxidizing agent as oxygen, gold interacts under rather difficult conditions.
In theory, we cannot reject the hypothesis that gold is magnetic. The fact is that gold is primarily a metal. Jewelers distinguish three groups among metals:
- ferromagnets - a group of metals that are easily influenced by a magnetic field;
- paramagnetic - metals that are magnetic, but not so well;
- Diamagnets are metals that are not magnetic at all.
It is believed that gold is a classical diamagnetic material.
To test alloys, this characteristic of gold is used.
Pure precious metal alloy is never used to make jewelry. Other metals must be added to its composition. This is done so that the decoration becomes wear-resistant. As mentioned above, pure gold easily changes shape under the influence of physical force. In order for the jewelry to be worn for a long time and not be manipulated, it needs to be made more rigid. Copper, zinc, nickel, platinum or palladium are used as additional metals.
Now that we know that other metals are deliberately added to the alloy, the question arises whether such an alloy can be magnetic.
If we talk about metals such as iron, steel, nickel and cobalt, then they are quite strongly exposed to the action of a magnetic field. Copper and aluminum are less affected by the magnetic field. The metals contained in the alloy will determine its ability to be magnetic.
Interesting fact! Metals such as silver, pure gold and bismuth repel magnetic fields. If you take gold with a purity of 585, where 58.5% is gold, and the remaining percentage is made up of additional metals (copper, silver), then such an alloy will still be weakly magnetic. These properties of gold can be used to determine whether what you are looking at is a fake.

If you buy gold secondhand or from an unverified store, use as many methods as possible to ensure the authenticity of the product. The main thing is not to try too hard, so as not to spoil the soft metal.
