How to choose a search magnet. Which search magnet to choose? Search Magnet Care

There are two types of search magnets: double-sided and single-sided. They also differ in size for each type from F 120 – F 600*2. When a person first encounters such diversity, he involuntarily asks himself the question - which magnet to choose? Below we will try to figure this out.

All search magnets are marked F (strength) and a number indicating the adhesion force of this product. For example, F 400x2 - adhesive force of 400 kg, and the designation x2 means that the magnet is double-sided. It is worth remembering that this is a “relative” adhesive strength, in fact it may differ, everything will depend on the metal to which the magnet is attached. The adhesion force is calculated: when the magnet contacts its entire area with a thick (at least 1 cm) polished steel plate, it is torn off strictly perpendicular to the surface. Under ideal conditions this search magnet holds more than 500 kg. It is difficult to achieve such results in magnetic fishing. Most often, the metal in the water is uneven, rusty and dirty; the magnet clings to it only with one edge, and not with its entire surface. Therefore, the magnet breaks off when pulling out a small piece of iron weighing only 40-50 kg. This is where everything will depend on the size of the search magnet; the larger it is, the better it will stick to the iron. This applies to “catching” large metals. If you plan to search for coins, spinners, etc., then a small one like F 200 will do the job. If you are looking for scrap metal, then search magnets from F 300 to F600 are best suited for this. Which one should you choose? It all depends on your physical and financial capabilities. Everyone can throw an average search magnet F300, F 400, F 600, but F400x2 or F600x2 will be more difficult without good physical strength. preparation. Keep in mind that the price of a search magnet depends on its size; the more powerful the magnet, the larger it is in size, and the price will be higher. An expensive magnet will pay for itself in 3-4 “catch”, because with it you will catch much more scrap metal than with a small one. If you are going to look for metal in large quantities, then buy a large magnet; if it catches something, it will hold it tightly.

Double-sided or single-sided magnet?

We’ve figured out the strength of search magnets and their sizes, now let’s see how double-sided and single-sided magnets differ. From the name it is already clear that it has one working surface - two. Double-sided has two holes - central and side, for attaching an eye bolt. A single-sided search magnet is more suitable for searching from piers, bridges, boats, as well as for searching in wells. A more universal search magnet is double-sided. It can be cast from the shore (the eyebolt is screwed into the side hole), as well as from bridges and boats (the eyebolt is screwed into the central hole).

Search magnets today are gaining great popularity not only among novice treasure hunters, but also among professionals. Naturally, a magnet cannot replace a treasure hunter, but with its help you can also make many amazing finds.

If a treasure hunter is actively used on land, then search magnets in the vast majority of cases are used to search for archaeological valuables at the bottom of rivers, lakes, crossings, etc.

It is necessary to think in advance about what finds can be found in a particular location. Based on their weight, you should choose a search magnet. They start at 120 kg, but can also reach 600 kg.

At the same time, the weight of the search magnet is no more than 1.5 kg. These figures indicate how heavy a load a magnet can not only lift, but also hold for a long period of time.

• by lifting weight;
• by price;
• by the number of eye bolts, etc.

In particular, the eye bolt can be screwed not only into the plane of the magnet, but also into its end part. The cheapest search magnets are single-sided. They are less effective naturally.

Double-sided magnets are more expensive. All of them are available at affordable prices on the website ndfeb-magnit.ru.

Of course, the most affordable search magnets are Chinese. However, if we are talking about a truly effective search, then you can refuse them. Of course, search magnets can be used to clear the field of small metal objects on the surface.

This is done so as not to break out with a shovel at every signal from the metal detector. Chinese analogues are also quite suitable for these purposes. But if the work is to be done at great depths, where the find is definitely covered with a large layer of silt and rust, it is better to rely on high-quality magnets.

In particular, a Russian manufacturer, which has production facilities in Kaluga (RedMag), produces magnets for the space industry. There is no doubt about their quality.

Of course, they are much more expensive than their Chinese counterparts. But with the latter, you will be able to pass by a sensational find, when a domestic product will allow you not only to detect, but also to pull an object weighing up to 600 kg to the surface.

Poryvaev will clearly demonstrate different kinds neodymium search magnets from a Russian manufacturer:

Every day a popular hobby is gaining momentum - searching for antiquities using a metal detector. Beginners are afraid to invest normal money in purchasing quality equipment. But based on my experience, I would like to note that only by investing money in quality things you get the expected result. Today there will be no long and tedious stories about all the benefits of quality attributes. Now I want to talk about search magnets, since investing in good magnet, you get two necessary search tools at once: a device for detecting and quickly removing any metal debris and a device for lifting metal products from the bottom of reservoirs. And there are a lot of relics hidden in the water.

When purchasing a search magnet, you should first decide on its purpose. If you need it for searching on land or vertical searching at the bottom of a reservoir or exploring the bottom of old wells, then it will the best solution purchase a one-sided magnet, that is, with one magnetic surface. This magnet is cheaper. But if you decide to purchase a universal tool, then you should buy a double-sided magnet with a side eye bolt.

I will not list the obvious advantages of this product, but I will say that with the use of such a device, the number of finds increases significantly. This is primarily due to the fact that when moving horizontally along the bottom of the reservoir under study, the magnet goes to a certain depth into the mud with the lower surface, and with the upper surface it collects all metal objects from the clogged bottom. This is a very important factor, since a magnet can attract small metal particles from a distance of no more than 15 cm. So, it’s clear: it’s better to buy a double-sided neodymium magnet. If you are planning to approach the purchase seriously, I advise you to familiarize yourself with the assortment of search magnets in the Mir Magnitov store - the largest niche store in the Russian Federation.

Places to find relics

The best places with the largest number of valuable finds are old bridges and military crossings. Good results are obtained from studies of mill whirlpools and pre-revolutionary wells. Sometimes even studies of drains and garbage pits and station toilets yield impressive results! After all, search magnets even magnetize jewelry containing a ligature. And what has never happened before: some thief, escaping from law enforcement agencies on a train, jumped out at the station and got rid of direct evidence by throwing it into the toilet - no one will swim there and look for it.

How to use a search magnet correctly

When buying a magnet with a high attractive force, which is written on the magnet in numbers after the letter F (this is the tearing load in kilograms), you should not worry about the possibility of being left without a magnet if it sticks well to the smooth surface of thick metal. For these cases, there is an eye bolt, by screwing it into the body of the magnet you will gradually tear it away from the surface. If the load is very large, as a rule, such cases occur with units with a power of 400 kg or more, you can use a lever to turn the eye bolt.

Don’t worry if a car suddenly ends up at the bottom, because its body is made of thin metal, and the magnet won’t stick to it too much. But you should definitely choose a climbing cord with a three-fold safety margin in case of snags.

Investing in a search magnet is a promising business, since the rare earth metals that make up its composition are only growing in price every year.

A neodymium magnet demagnetizes very slowly. On average, about 1% per year, provided the integrity of the case. Monitor the condition of the magnet coating and under no circumstances heat it above 80 degrees.

It is very convenient to use instead of a pinpointer: the batteries do not run out, and there is no unnecessary noise. It is better to use it when searching with a metal detector, storing it in a fabric bag. With the help of a bag, it will not become clogged and will be less susceptible to mechanical damage.

Neodymium magnets are very fragile and when chipped or broken they lose a lot of power.

People using pacemakers should handle them very carefully.

A very useful thing in everyday life, since you can always very quickly find a small metal object and filter liquids from chips.

Good day, comrades!

Search magnets appeared on Survival... I think simple tips about his choice will be useful to many. The topic is new after all.

The 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 difficult to reach with metal detectors, etching rivers and other bodies of water, clearing the soil of small iron, preparing a place for searching with a metal detector, removing iron from littered areas, as well as when digging up an old foundation, determining the magnetism of stones (to find out whether they are meteorite fragments).

Search magnet- this is a completely galvanized device, consisting of a body (N10 steel) and, in fact, the magnet itself (Fe-Nd-B alloy), most often equipped with a special eye bolt to which the cable is attached. The gap between the body and the magnet is filled with special epoxy glue, which allows the device to be used in both fresh and sea water.

The search magnet can be stored and used at a temperature of ±50°C. When the magnet is heated above 80°C, it may become demagnetized. If temperature conditions are observed, no more than two percent of the nominal value is lost over ten years of operation of the magnet.

Today's search equipment market provides a huge variety of magnets. The main thing is to choose a magnetic device from this variety that meets your needs and physical capabilities.

1. When choosing a search magnet, you must first of all be guided by its tearing force: 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 lifting force of this model). Most often, treasure hunters prefer 80-400 kg magnet models. Moreover, magnetic devices up to 150 kg, called “expedition magnets” by professionals, are used to a greater extent for work on land, in particular for cleaning the surface of metal debris. And here is the main function magnetic devices over 150 kg., actually “search” ones, and consists of searching and lifting 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 eye bolts instead of one) are used extremely rarely by search engines.

2. The maximum magnetization force is achieved under ideal conditions: if the contact areas are located on a short 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, one also takes into account errors in the surfaces of objects associated with rust, irregularities, the thickness of the metal component, the magnetic properties of some metals (for example, relative to iron, stainless steel is somewhat weaker in magnetism), etc.

3. Also, when choosing a magnet, you should take into account the fact that a very heavy magnet will quickly tire you out, 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 millimeters, diameter - 120–220 millimeters.

We continue to disassemble the treasure hunter's equipment and today we will pay attention to this interesting thing, like a search magnet. What is this thing, how to use it, what can you find, show a video, how much it costs and which models are the “coolest” according to reviews from searchers - read in this article.

So, search magnets are designed to search for metal objects, most often with such a magnet they are searched in places that cannot be reached with a metal detector, for example, in wells, in water and other places where searching with a conventional metal detector is impossible for a number of reasons (it is dangerous to climb into an abandoned well or there is no metal detector - amphibians like, to search under water). Although I will immediately note that searching with a magnet is not a safe activity, just look at the first photo.

The search magnet is made of a special alloy of three elements - the main one is neodymium, also iron and boron. Most often, familiar searchers ask and want to buy neodymium search magnets. The magnet itself is hidden in a durable metal case (the case is galvanized so that it does not rust); for attaching a rope or halyard, there is a special bolt in the form of a ring at the top of the magnet or on the side (depending on the model). You attach a magnet to it and throw it into the water in the hope of finding something valuable. Just like in a fairy tale - and the grandfather threw a search magnet into the water and it caught a broken metal trough)) This is exactly how they work - they throw metal objects into the water and take out metal objects, which are then handed over to the ferrous metal or, if they are valuable, they are sold at a higher price as valuable items , having value. So if you are searching on a river or pond, it is better to take a magnet with a bolt fastening on the side, since you will be “dragging” the magnet along the bottom and it will go along the bottom with its entire surface. By the way, magnets can be single-sided or double-sided.

There are a lot of ways to use a search magnet; I have even heard of cases where metal modern money was taken out of fountains using such a search magnet. After all, a magnet is a magnet because it can only hook products made of metal or a metal alloy; to be precise, such alloys are called ferromagnetic. For example, modern metal 10-ruble coins are made of steel in a non-ferrous metal shell, they cling perfectly to a magnet and you can catch a lot of them if you sit in right place)) If you want some advice, go to the beach, take a search magnet in your hand and move it over the sand - you will attach so many modern little things that after a couple of trips you will pay for such a magnet and still have enough left for beer.
So people who buy magnets make money by finding ferrous metal and other metals that are magnetic.

Another way to use a search magnet is perfect for attic search lovers. If you’ve ever tried to look for coins in powder, you know that there’s so much metal there that you’re simply blown away by the squealing of the detector. Therefore, in order to at least slightly reduce the amount of left-handed metal in the powder and prepare the soil-powder for searching with a metal detector, first walk through the powder with a search magnet. Be sure that you attach so many rusty nails and other iron that searching later with a metal detector will become much easier. Here's tip number 2 for using a magnet.

This strategy is also applicable for loose soil; I already talked about sand when searching on the beach. But sand is not only on the beach, there are fields where you dug for coins and the soil there was sandy. So use a search magnet there too.

Types of search magnets

The most important characteristic of a search magnet is its carrying capacity. if you were interested in them, then you know that they come in sizes of 200, 300, 400 and more kilograms. This means that the magnetization force is such that you can lift through the air a weight equal to the carrying capacity of the magnet. However, you should not think that if you threw a magnet into the water and hooked a powerful piece of iron at 300 kg, you will not be able to lift it with a magnet at 300 kg for a number of reasons - the first is that lifting a weight through the air is one thing, and the second is that pull it along the surface, where friction is also involved. This time. Secondly, if the iron is rusty, then it magnetizes much worse than new one. So it’s even more difficult to pull out rusty iron, and if the magnet is also low-power, then it’s a pipe altogether.

Next, it’s worth saying a few words about safety precautions, because some treasure hunters are so preoccupied with their hobby that they completely stop thinking with their own heads. Well, you have to come up with this - put your fingers between the search magnet and the iron pipe. The pipe could be magnetized and hit with such force that your fingers break once or twice. Therefore, think with your head about what you are doing and do not put your fingers or other parts of your body (think about your future children)) between the surface of the magnet and the metal object.

Also, when you carry a search magnet, stay away from iron objects, and in particular your car. Otherwise, if you are magnetized to it with such force, you will twist your hand (if you are carrying it by the bolt and inserted your finger into the ring) and put a big dent on your favorite car.

Manufacturers also say that the magnet affects Cell Phones and other electronics, and electronics influence them. So, away with cell phones when you are “fishing” with a magnet.

If you buy a high-quality search magnet with a reserve of power and carrying capacity, follow safety rules and “fish” in promising places, then searching with a magnet will be no less exciting than searching with a metal detector. It’s really interesting when you throw it in, you feel it “takes the bite” and you drag it away, not knowing what you got there. Adrenaline is also present))

Among the most popular, it is worth noting the F series models from the city of Kaluga.

Price for search magnets

F 120 - for 120 kilograms, costs approximately 1300 rubles. There are also models for 150, 200, 300, 400 and 600 kg. The price is roughly like this:
150 kg - 2000 rubles
200 kg - 2700 rub.
300 kg - 3500 rub.
400 kg - 4300 rub.
600 - 6400 rubles

As you can see, the more powerful the magnet, the higher its cost. Therefore, buy search magnets according to your ideas; if you decide to “catch” small things on the beach, then the cheapest one will do; if you are looking for treasure, then take it with a reserve of at least 400 kg. Good luck with your search, colleagues.

And finally, a video of how people “catch” rifles and other joys of war diggers with a magnet.)) Yes, they catch everything that is made of metal, starting from ordinary pieces of iron and ending with the echo of war - grenades, mines, cartridges. So be careful out there people and good luck. As fishermen say - no bite, no catch.

And here they coolly picked up an old iron)) And then a grenade nahh..))
