How to choose a search magnet and what to do with it? The basics of working with a search magnet Search magnet, what is it for.

Hello dear blog readers. Today I’ll tell you about another search. But he was unusual. I have long noticed a trend of increasing popularity of search with a search magnet. are designed to search for ferromagnetic metals; noble metals - gold, silver - are out of the question. Unless you are incredibly lucky and items made of precious metals will be stored in an iron box. Also, these magnets react well to modern and Soviet coins, due to the presence in them of a high percentage of metals that react to the magnet. If you are attracted to this type of search, which is quite a budget option, because magnets are several times cheaper than metal detectors, remember the rules for working with a magnet, their list is very large. First of all, this is safety - be careful when removing small objects from the magnet - you can cut yourself.

It is worth keeping these devices away from electrical appliances, and most importantly, do not bring your hand to the attracting surface when there is a heavy object within its range of action. Beware of heating the magnet, this will have a detrimental effect on its further operation.

Well, be careful when buying devices - they are very often counterfeited.

There are varieties of search magnets, which depend on the force of attraction and the area of ​​attraction. Thus, there are one-sided and two-sided magnets. I stocked up on one of the most reliable ones - . This type of magnet is especially strong and has a constant attraction. These devices are unpretentious to search conditions, but quickly lose their presentable appearance - they are overcome by rust. However, these devices are usually equipped with an anti-corrosion coating, so feel free to use them in water. The main advantage of neodymium search magnets is their high load capacity under constant traction conditions. A serious drawback is the price, which has jumped sharply since 2009. Well, don’t forget that transporting these devices when using postal services is illegal.

So, a good place to search with this device is watery areas where a large number of people have recently been present. These are various abandoned wells, mines, lakes and beaches. I didn’t want to take risks with wells, so my friend and I went to a semi-abandoned village, Popazdra, whose main advantage was its abandoned beaches. So, having arrived at the place, I want to note that transporting a magnet is not an easy task. Don't forget to place it in a special box with non-magnetic materials, which is what we did. If this is not the case, place a board or something plastic under the part that attracts it.

Well, the report itself

Thus, we got to the place and prepared for the search by preparing a magnet. Using the magnet is quite easy - just move it over the surface to be studied. If you want to search in water, tie a magnet to a rope and lower it into the water. Within a few hours, among our finds there were no particularly valuable things - a bunch of small coins that are not particularly valuable. But I still wanted to continue the search in case the magnet showed its best side. So, having set our minds, we continued to explore the beach, slowly going into the field. And there luck smiled on us - we found several helmets of German and Soviet soldiers, and having thrown the magnet further into the water, swam on a small boat away from the shore - we pulled out the iron base of the wheel of the World War II time machine.

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:

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 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.

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.

Magnetic properties of various metals

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

ferromagnets

paramagnets

diamagnetic materials

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

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

And finally, diamagnetic materials. Such alloys are extremely difficult to respond to magnetic fields 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 pick up.

Is it possible to find gold with a magnet?

As already discussed earlier, jewelry and coins with gold can be lifted, but it is very problematic.

It is impossible to get pure gold with a magnet.

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

You don’t need to think that all “fishing” will come down to throwing a magnet at a distance and pulling it back by the cable. To increase your chances of success, you need to follow several rules for working with search magnets.

1. Practice throwing in an open area with soft ground to evaluate your strength and “shoot.” Otherwise, the magnet may fly away to a different place than expected and even injure you.

2. Take care of the cable; it should be strong and bright (in case it gets tangled in snags, it will be easier to untangle). Choose the optimal length so that the cable does not get tangled. This depends on the depth of the reservoir, which, according to your mind, needs to be determined in advance.

3. To “fish” with a magnet, you will need a boat, and it’s better not an inflatable one, because a large pile of rusty objects can damage the watercraft.

4. Do not keep the magnet stationary in one place. This could cause it to magnetize something so heavy that it breaks the cable.

5. The best way is to throw the magnet and pull it back at medium speed (not too fast). You can also simply walk near the shore in swamp boots, dragging a magnet behind you.

6. If the bottom of the reservoir is heavily silted, then it makes sense to attach the search magnet not to the cable, but to the pole, and deepen it by pressing the pole forcefully.

7. After each cast, in some reservoirs you have to remove a layer of scale from the magnet, so take gloves and rags.

8. After repeated use, the galvanized layer usually peels off the surface of the magnet, and it begins to rust. To delay this phenomenon, it is advisable to clean and dry the magnet after each search session.

9. It is better to transport the magnet in a wooden case, and not keep it close to electronics. The mobile phone will definitely break in an unequal battle with neodymium.

But what can you catch with a magnet?

Catch with a magnet in a lake near one of the European towns.

“Yesterday I caught three scuba divers, two divers and one man with balls of steel using this kind of gear. The latter resisted the longest,” says one of the searchers.

Jokes aside, you won’t find gold-diamonds with a search magnet - precious metals are not magnetic. However, by following the basic rules, you can catch up to 100-130 kg of scrap metal in a couple of hours in a city or rural reservoir. If you hand it over, it will turn out to be a good amount.

You can buy a powerful neodymium magnet, which can lift hundreds of kilograms at a time, in

Article about using a search magnet from our buyer

I purchased my NEPRA 200 kg double-sided search magnet for $40. The price is reasonable, although it seemed to me that 200 kg was a lot to start with. I had no idea how, what or where to catch. Following some simple advice from YouTube, I also bought 20 meters of cable and gloves. That's all. None of the search engines wanted to share the secrets of successful fishing. So I had to figure it out on my own. There are many videos online about magnet fishing. Finders mainly work with magnets in lakes, ponds, old flooded quarries, wells and low-water calm rivers. My situation was somewhat different. The river I chose to conduct my search was quite deep and fast. This is where the first problems arose. The current quickly carried away the magnet, preventing it from immediately sinking to the bottom. As a result, in one cast it was possible to explore a relatively small area of ​​the bottom. Other difficulties arose when I started trying 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 the magnet along the entire length of the cable. At the same time, if it was possible to grab a large thing, the current immediately tore it back. In such cases, the cable begins to vibrate strongly, and you can 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 is still carried away along the entire length of the cable, and you have to guide it along the bottom, collecting the rope, then it is even more convenient to do this if the magnet goes flat. It’s easier to fish from the bridge near the shore, but you mostly find real garbage there. Under such conditions, it makes sense to throw the magnet vertically only with great force. It turns out that if the river bed is not too wide, then it is best to examine the bottom near the bridge, throwing a magnet from the shore. The situation changes completely if you are fishing 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.

I have been convinced many times that algae is the worst enemy of search engines. There is nothing worse than feeling when a magnet has securely grabbed an interesting thing, after which it gets stuck in the algae, and the purest magnet appears in the light of day. Therefore, if possible, you need to stay away from algae. The same goes for the silted bottom. In this case, the magnet will twitch with “false bites” during wiring, but it will not be able to properly magnetize to the thing, nor will it be able to tear it out of the captivity of mud and dirt. There is little pleasure in such fishing. Therefore, it is very important to choose a suitable location. I managed to find such a place, and the banks of the river here were concreted, as was the bottom. It would be difficult to imagine a more convenient location. The tactics chosen were as follows: you select 10 meters of shore and throw a magnet along the entire length of the rope, at approximately an angle of 45 degrees to the shore. It turns out there is no point in throwing it further. All things are basically not very far away. Another feature that I noted is that things are in “piles”. Having found such a pile, you need to fish it thoroughly, even if you can’t catch something right away. It often happens that if you pull out some voluminous thing from these deposits, then the rest of the things will be taken out one after another. This kind of fishing is similar to playing spillikins. Fishing on concrete banks turned out to be inconvenient in only one way. The cable, tied to the eye bolt, quickly wore out when running over a rough surface. I had to bandage and cut the end every 3-4 “hunts”. The solution was found using ordinary electrical tape tightly wrapped around the knots.

The most interesting thing is to pull out something voluminous or unusual. My 200 kg magnet was quite sufficient for these tasks, although now I would choose a more powerful magnet. It happens that a magnet grabs a large object underwater so tightly that it can barely be pulled 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 attached to something that cannot be pulled out, you should change the angle of application of force to break the magnet. In most cases this works great. If you deviate even slightly to the side, 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 force, the magnet treacherously slips. To avoid this, you can also try changing the angle. It helps! Another important rule is to pull the prey continuously. If you magnetized a large thing and were able to move it, then you need to move it smoothly and without stopping. Once you stop, 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 long corner onto 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 I bought the magnet, I had no clear idea of ​​what I would do with it. Fishing has shown that it is mainly possible to get ordinary scrap metal from the bottom of the river: corners, fittings, spare parts for cars and other small items. It was stupid to throw it all back, so the metal was transported to a collection point. It was the scrap metal that allowed the magnet to be repaid. I can’t say exactly how many trips to the river this required. On average, in 1.5-2 hours of fishing it is possible to collect 40-60 kg of iron. But this is so, prose... In addition to this, the magnet caught: an axe, 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 machine gun cartridges, several cartridges from a large-caliber tank machine gun, and even a tank shell. All this was carefully returned to the bottom. Fishing with a search magnet is quite an exciting activity. There are some nuances here, and no one can guarantee that you won’t get bored with it tomorrow; besides, it’s unlikely that you’ll be able to make money from it. The only way to make money is by targeting scrap metal and acquiring a more powerful magnet. However, who knows what will fall for you?

Why do you need and how to choose a search magnet?

You've probably already noticed that a mysterious group of products has appeared in the assortment of stores for search engines. There are very few products in this group and they are all called Search Magnets. Let's figure out together why a search magnet is needed.

Why are search magnets needed?

First of all, a search magnet is designed to search places hidden from conventional search methods. For example, using a search magnet you can search the bottom of a well, pond or small river. It is enough to tie a strong rope or cable to a search magnet and lower it into the magnet at the bottom of a reservoir or well. If there are objects made of iron, nickel and other magnetic materials at the bottom, then the search magnet will be magnetized to them and they can be easily retrieved without plunging into the water. But what interesting things could be hidden in a village well or the bottom of a river in the area of ​​the crossing? Very interesting household items, as well as things that they tried to hide more reliably, for example, weapons hidden by deserters, partisans and other individuals with a darker past.

One more area the use of search magnets - clearing the intended search site of iron debris. It is enough to drag a search magnet along the surface of the earth so that it collects from the surface all the nails, pieces of steel wire, steel plugs and other search debris that litter fields, abandoned houses and settlements.

A search magnet can also be used when searching with a metal detector. If the metal detector signal disappears after you have dug a small hole, then a search detector will help you quickly find iron “garbage” in the screening or in the hole. What should you know when choosing a search magnet? The most important characteristic of a search magnet is its magnetic strength. In order to make the value of the magnetic force more clear to the buyer, it is expressed in kilograms. Search magnets have a magnetic force of 60 to 600 kilograms. The most popular magnets among search enthusiasts are magnets for 200, 300 kilograms; they have a reasonable price and are easy to use. More powerful magnets of 500 kilograms or more are in less demand. It seems that you can get half a ton from the bottom of the river. But such powerful magnets are needed for more precise fixation to thin metal with curves or to small metal surfaces. For the accuracy of the description, it is worth adding that testing and determining the magnetic strength of the search magnet takes place on a clean milled steel sheet 8-10 mm thick. Therefore, a search magnet must be purchased with a reserve.

When choosing a search magnet you need to choose a magnet that has a device for removing the magnet from the piece of metal on which it is magnetized. Otherwise, removing the magnet from the metal will take much longer than the search itself. Most often, the device for removing a magnet from metal is an eye bolt. The eye bolt performs two roles at once - a convenient place for attaching a rope or cable and a simple device for removing a magnet from metal. It is enough to screw the eye bolt all the way into the body of the search magnet and it can be easily removed from the found metal.

Search magnets come in single- and double-sided types. Double-sided magnets are more convenient and more efficient, due to the fact that they can be magnetized to the “target” by two sides, rather than one.

Selecting accompanying equipment for working with a search magnet

If you are going to use a search magnet to search at the bottom of reservoirs or wells, as well as to lift finds to the surface, then you will have to additionally purchase a strong rope and a winch for the magnet! Yes, a winch! How are you going to get your magnet out of the bottom of the swamp if it gets caught on a sunken tank? Of course, none of the search magnets will pull out a tank; it’s like dragging a “hippopotamus out of a swamp.” But you also can’t leave the magnet at the bottom because the rope breaks. Therefore, if you purchased a 200 kilogram magnet, then it is advisable to use it with a 250-500 kilogram rope and a similar winch. And of course, don’t forget to take with you a key or a strong wrench for screwing in the eye bolt, otherwise you risk returning home with a magnetized anvil
