How to search with a magnet in the ground. search magnet

Article on using a search magnet from our customer

I bought my double-sided NEPRA 200 kg search magnet for $40. The price is acceptable, although it seemed to me that 200 kg for a start is a lot. I had no idea how, what and where to catch. Following simple advice from YouTube, I also bought 20 meters of rope and gloves. That's all. None of the search engines did not want to share the secrets of successful fishing. So I had to figure everything out on my own. There are many videos on the net about fishing with a magnet. Basically, seekers work with a magnet in lakes, ponds, old flooded quarries, wells and shallow calm rivers. My situation was somewhat different. The river I chose for my search was quite deep and fast. This is where the first problems arose. The current quickly demolished the magnet, preventing it from sinking to the bottom immediately. As a result, in one cast it was possible to explore a relatively small area of ​​the bottom. Other difficulties arose when I began to try to fish from the bridge.

As already mentioned, fishing on the bridge turned out to be a thankless task. When casting from the middle, a strong current immediately carried away the magnet for the entire length of the cable. At the same time, if you managed to grab a large thing, the current immediately tore it back. The cable in such cases begins to vibrate strongly, and you directly feel how the caught thing stubbornly slides off the “hook”. As a result, only compact and small things like locks or cartridges can be pulled to the surface. At the same time, due to the speed of the flow, there is practically no reason to lower the magnet vertically. If it gets carried away the entire length of the cable anyway, and you have to lead it along the bottom, collecting the rope, then it is even more convenient to do this if the magnet goes flat. Fishing from the bridge near the shore is easier, but there is mostly real garbage. Under such conditions, throwing the magnet vertically makes sense only with great effort. It turns out that if the riverbed is not too wide, then it is best to examine the bottom near the bridge, casting a magnet from the shore. The situation is completely different if you fish in calm waters. Here you can lower the magnet to the bottom and calmly move it parallel to the surface until it catches the metal.

Many times I was convinced that algae is the worst enemy of search engines. There is nothing worse than feeling when a magnet has securely grabbed an interesting little thing, after which it gets stuck in algae, and a pure magnet appears in the light of day. Therefore, if possible, you need to get away from algae. The same with the silted bottom. In this case, the magnet will pull “false bites” during wiring, but it will not be able to properly magnetize to the thing, nor will it be able to pull it out of the captivity of mud and dirt. There is little pleasure in such fishing. Therefore, it is very important to choose the right place. I managed to find such a place, while the banks of the river here were concreted, like the bottom. It was hard to imagine a more convenient location. The tactic was chosen as follows: you choose 10 meters of the shore and throw the magnet along the entire length of the rope, approximately at an angle of 45 degrees to the shore. Throwing further, as it turned out, does not make sense. All things are mostly not very far away. Another feature that I noted is that things lie in “heaps”. Having found such a pile, it must be carefully caught, even if something cannot be caught right away. It often happens that if you pull out some bulky thing from these deposits, then the rest of the little things will be taken out one after another. Such fishing is similar to the game of spillikins. Fishing on concrete banks was inconvenient in only one way. The cable, tied to the eyebolt, quickly wore out when guiding over a rough surface. I had to bandage and cut off the end every 3-4 “hunts”. The solution was found using ordinary electrical tape wrapped tightly around the knots.

The most interesting thing is to pull out something voluminous or unusual. My 200 kg magnet proved to be quite enough for these tasks, although now I would choose a more powerful magnet. It happens that the magnet grasps a large thing under water so tightly that it can hardly be torn off. In such a situation, the main thing is not to overdo it, otherwise you can break the cable and be left with nothing. If the magnet is stuck to something that you can't pull out, you should change the angle of the force to rip the magnet off. In most cases, this works great. It is worth even slightly deviating to the side, and the obstacle immediately disappears. The same law, only applied in reverse, applies when you grab something big. This feeling is familiar to all search engines - you feel that the magnet is securely seated, but its strength is not enough, and when you start to pull with effort, the magnet treacherously slips. To avoid this, you can also try changing the angle. It helps! Another important rule is to pull prey continuously. If you magnetized a large thing and were able to move it, then you need to carry it out smoothly and without stopping. One has only to stop, and no one will guarantee that you will be able to move it again. Thanks to this technique, I was able to pull a two-meter corner on the shore, at the end of which there was an impressive concrete boulder. The total weight of the find was more than 50 kg!

When buying a magnet, I did not have a clear idea of ​​​​what I would do with it. Fishing showed that basically it is possible to get ordinary scrap metal from the bottom of the river: corners, fittings, machine parts and other trifles. Throwing it all back was stupid, so the metal was transported to a collection point. It was scrap metal that made it possible to recoup the magnet. I can’t say exactly how many trips to the river were required for this. On average, in 1.5-2 hours of fishing, it is possible to gain 40-60 kg of iron. But this is true, prose ... In addition, the magnet caught: an ax, a crowbar, a crowbar, an old iron, a meat grinder, a candlestick, a rake, a pick, various knives, screwdrivers. This is what I managed to remember offhand. We also managed to fish out several dozen automatic cartridges, several cartridges from a large-caliber tank machine gun, and even a tank shell. All this with care was immediately returned to the bottom. Fishing with a search magnet is quite an exciting activity. There are some nuances here, and no one will guarantee that tomorrow you will not get bored with it, in addition, it is unlikely that you will be able to make money on it. It will be possible to earn money only by aiming for scrap metal and acquiring a more powerful magnet. However, who knows what will fall on the bait for you?

Usually, powerful magnets are designed to search for precious metals. The 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 black metal.

The article describes the device of the magnet and the basic principle of operation. It will also figure out what exactly with its help you can find and how to find expensive alloys. Explain in detail what are ferromagnets, paramagnets and diamagnets. In addition, valuable tips and tricks will be given that will greatly simplify the search for valuable items.

Search magnet device

This device consists of a steel case, inside which is a neodymium magnet. It is made from a rare alloy containing neodymium, iron and boron. Such a connection has a powerful attracting property. Despite its compactness, it is able to hold things ten times its own weight.

For the convenience of getting various things, a special mount is provided in the case. It is screwed into the body of the magnet by means of 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, which is firmly screwed into the body. The whole structure has a reliable foundation, and in this case, it is not scary to lift any expensive and heavy thing.

Principle of operation

The search magnet has rather meager functionality. The main task of such an object is to attract as many metal objects as possible to itself. But the device copes with its main task more than well. Due to its unique design, it has great strength, and is able to hold rather large objects, as well as objects containing gold or silver, which ordinary magnets do not take.

This is especially useful when getting things out of wells, funnels and various pits. It is also good to use such a thing under water. In water, all objects are affected by great resistance, and picking up any object becomes a rather laborious task. But with a neodymium magnet, finding and retrieving such items is greatly simplified.

What items can be found

In the question of what things can be found with 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 body of the magnets, 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, and many rare Soviet coins.

Powerful magnets can attract metals such as:

aluminum

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 jewelry, expensive jewelry, various metal boxes, and sometimes even expensive mobile devices (on the beach). This is about finding things on land.

As for water, you can also find many valuable items, including gold jewelry. Also, thanks to superstition, you can raise a fortune of coins from the bottom. Moreover, you do not need to get coins from the city fountains, since there are quite a few abandoned wells that no one needs, but keep precious things in themselves.

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 not everything is so bad, thanks to all the power of the neodymium alloy, it is possible to get some jewelry. Such items 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, and gold jewelry has greater durability. But the most important thing is that the ligature allows you to be magnetized, and makes it possible to search for 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. Usually jewelry made of gold or silver is stored in such cases. So walking around the attic or places like it, you can “get rich” well, in the truest sense of the word.

Magnetic properties of various metals

In order to go hunting for valuable metals, you need to know what exactly will be attracted to the magnet. Since metals have different magnetic properties, and some do not have at all. They can be divided into three groups:

ferromagnets

paramagnets

diamagnets

Ferromagnets are metals with some of the best magnetic properties. These metals are highly magnetic. These include black metal.

Paramagnets have the usual properties, they are readily attracted to a magnet, but they do not have the function of magnetizing. These include some alloys of jewelry and several types of non-ferrous metals.

And finally diamagnets. Such alloys are extremely difficult to succumb to a magnetic field and greatly complicate the search for truly precious things. Diamagnets include gold, silver, aluminum, patina and other metals that even the strongest magnet does not take.

Can you find gold with a magnet?

As discussed earlier, jewelry and coins with gold can be raised, but very problematic.

Pure gold cannot be obtained with a magnet.

But if various factors are favorable, such as an iron box or paramagnetic jewels lying nearby, then there is a chance to find it. Basically, only jewelry with gold content, such as bracelets, earrings and rings, can be caught on a magnet. The best place to search is a sandy beach, wells, as well as the sea or river bottom, where a large number of people swim.

Good day, comrades!

Search magnets appeared on Survival... I think that simple tips on choosing it will be useful to many. The topic is kind of new.

Mass production of powerful magnets for household and industrial needs began more than seven years ago. At the same time, magnets found recognition among treasure hunters, who began to use this device for their own purposes, such as: searching and lifting metal objects in places hard to reach for metal detectors, etching rivers and other bodies of water, cleaning the soil from fine iron, preparing a place for searching with a metal detector, removal of iron from littered areas, as well as when digging up an old foundation, determining the magnetism of stones (to find out if they are fragments of a meteorite).
search magnet- This is a fully galvanized device, consisting of a body (N10 steel) and, in fact, the magnet itself (Fe-Nd-B alloy), most often equipped with a special eyebolt to which the cable is tied. The gap between the case and the magnet is filled with a special epoxy adhesive, which allows the device to be used both in fresh and sea water.

The search magnet can be stored and used at +/-50 °C. If the magnet is heated above 80 °C, it may become demagnetized. Subject to temperature regimes for ten years of operation, the magnet loses no more than two percent of the nominal value. Today's search equipment market provides a huge variety of magnets. The main thing in this variety is to choose a magnetic device that meets exactly your needs and physical capabilities. 1. When choosing a search magnet, first of all, it is necessary to be guided by the strength of its separation: the minimum holding weight is 30 kg, the maximum is 800 kg. The weight is indicated in the name of the model, for example, F=400 (where 400 is the pull-off force of this model). Most often, treasure hunters prefer 80-400-kilogram models of magnets. Moreover, magnetic devices up to 150 kg, called "expeditionary magnets" by professionals, are used to a greater extent for work on land, in particular for cleaning the surface of metal debris. But the main function of magnetic devices over 150 kg., actually "search", is to search for and raise iron objects from the bottom of reservoirs, rivers, lakes, etc. Eight hundred kilogram magnets, which are very bulky and inconvenient (due to their rectangular shape and two eyebolts instead of one), are extremely rarely used by search engines. 2. The maximum magnetization force is achieved under ideal conditions: if the contact areas are located at a small distance and perpendicular to each other, the object has a clean and smooth surface and the thickness of its steel coating is 5 millimeters. Thus, when choosing a magnet, the errors of the surfaces of objects associated with rust, irregularities, the thickness of the metal component, the magnetic properties of some metals (for example, stainless steel is somewhat weaker relative to iron), etc. are taken into account. 3. Also, when choosing a magnet, one should also take into account the fact that a very heavy magnet will quickly tire, so it is better to give preference to a magnet that has less weight but more power.
The most optimal and in great demand search magnets have the following characteristics: F = 80-400, weight - 130-1400 grams, height - 18-34 mm, diameter - 120-220 mm.

The search for coins and treasures with a “search magnet” in the water (river, well, lake, etc.) and in the ground (in the backfill of the attic, beaches) is gaining great popularity. Why?

In this article I will tell you: which coins can be magnetized and which are not? what are magnets? How to search with a search magnet? What can be found with a magnet, and in what places can you find something worth 100%?

Whoever decides to deal with the delivery of the found ferrous metal, we also advise you to read our article.

What metals are attracted by the "search magnet"?

The search magnet will not attract pure precious and non-ferrous metals (gold, silver, copper, aluminum), since they are not “ferromagnets”. The magnet can attract: iron, cast iron, steel, nickel.

Those who are going to use a “search magnet” to look for coins and treasures, as a consolation (to add optimism, so to speak) I want to say that: firstly, the coins can be in an iron case-box (according to statistics, all the treasures found were there), and secondly where did you see coins that were made from the same metal?

In many cases, this is an alloy of ferrous metal with non-ferrous (the photo is one hundred percent proof of this, coins on a magnet, most likely a copper-nickel alloy, are hard to see, but I think Tsarist Russia).

Precious metals are a different matter, and gold and silver are reluctantly fused, one might even say nothing.

Modern coins are especially well magnetized, some Soviet coins (mainly 1, 2, 3 and 5 kopecks), some Tsarist ones.

The magnetic properties of the coin are the higher, the more iron or other ferromagnet in the copper alloy (well, at least 1.0 - 2%).

As for the magnetic Royal coins, I recently read a short article about this (I don’t remember where), that a lot of copper magnetic coins were minted at the Yekaterinburg Mint at one time.

The reason for this was that copper with a high iron content was mined in one of the mines, so coins made from this ore are attracted to the full by a magnet.

It is also known that some coins of Anna Ioannovna, and coins of 1 and 2 kopecks of 1811-1843 are magnetic, and the latter are generally a triple alloy (copper-nickel-zinc).

I advise you to have a very strong magnet (preferably neobium) to search for coins.

What are search magnets? Where can you buy them?

Search magnets have different weight holding strengths: 200 , 300 , 400 , 600 , or 1600 kg. Magnets can also be single sided or double sided. The second option is preferable, since the metal attraction area is available on both sides.

You can buy a magnet in the online store of search equipment, for example, double-sided with a force of 120 kg, it costs only 1.5 thousand rubles, for a magnet with a force of 600 kg, you will have to “fork out” for 5800 rubles.

The only obstacle to buying a search magnet is delivery (after all, under the terms of delivery by Russian Post, it is strictly forbidden to send magnetic materials).

The search magnet consists of three parts: a body, a magnet, and a bolt-loop (a cable or rope-rope is attached to it).

Safety precautions when working with a magnet are very important: do not insert any parts of the body between the magnet and the metal, as you can be severely injured (in some cases even breaks), during transportation, make sure that it does not come into contact with the metal parts of the machine, do not heat the magnet, because at temperatures above 80 degrees Celsius, it may demagnetize, after use, wipe it with a dry cloth to avoid corrosion.

Where to look to find something “worthwhile”?

You can search with a magnet: in natural reservoirs, wells, swamps, on sandy beaches, in powder in the attic.

There can be a lot of metal finds on the beaches: modern trifle (modern 10 rubles are especially well magnetized), keys, corks, etc.

In order to optimally search for valuables in the water, you need to take the choice of a “fishing” place very seriously. My advice to you is to look for a place of an old beach, or a place where, according to stories, people took water, washed, bathed.

Usually there is sandy soil, a convenient descent, a flat area of ​​the coast.

Also, if you live on the Middle Volga, you probably know that during the construction of the Kuibyshev Reservoir (the Volga flood), thousands of villages were flooded (people moved, or the villages were old and abandoned).

Also, do not forget the tradition of throwing coins into the sea on vacation in order to return again, or into the river “for good luck”.

Take old maps and overlay them on modern ones (), look for ancient flooded villages, buy a magnet and a boat, and go ahead to search for valuables.

By the way, if you hand over scrap metal along the way, you will always be in the black.

Finds in the water will be the following: nails, irons, knives, coins, rings, shovels, axes, fish hooks and other metal objects.

Good luck with your "catch". Read our blog...

Magnetism has long been studied by man, this useful quality of magnets has been widely used in various fields of activity. However, only due to the rapid pace of technological progress, magnets have recently become available to the general public. Thus, innovative developments have given rise to a new form of alloy - a neodymium magnet or search magnet, which has almost completely replaced the usual ferrimagnetic material. A new type of magnets is widespread and successfully used in everyday life, in the electrical field, in medicine.

A search magnet is an object most often of a round shape with a steel case, inside of which a neodymium core of one or another power is hidden, it is worth noting that the price of a search magnet will also depend on this. On one of the planes of the body there is a strong ring-shaped fastening earring - eyebolt. The mount is also necessary to separate a powerful magnet from a metal object it has discovered, for which you need to screw the bolt more tightly into the structure.

How to use a search magnet?

Many metal seekers, archaeologists, searchers of historical artifacts dream of buying a search magnet, since it has an undeniably many positive qualities. Using such a device, you can search for metal objects not only on the ground, whether it be soil, clay, sand or grass, but also in water bodies of any depth from small rivers to deep-sea lakes.

Security measures

You should be aware that when operating a search magnet, a number of safety measures must be observed:

1. The magnet is carried exclusively by the earring or in a special bag. So, you will exclude accidental magnetization to metal objects, for example, a car body or an iron garage door. This is not just a warning, it should be understood that such a magnet is extremely difficult to detach from flat surfaces of a large area, therefore the surface can be damaged.
2. In no case should you keep your fingers in the space between the working magnetic surface and a metal object in order to avoid injury.
3. Any objects with electromagnetic properties should be kept at a distance of at least 30 centimeters, be it electronic and even quartz watches, telephones, plastic bank cards.
4. The search magnet can be operated at temperatures up to 80 degrees, so avoid overheating. Otherwise, the magnet will lose its main quality - magnetization to the metal.
