How to properly store a search magnet

Search magnets: reviews, review, characteristics

As reviews of search magnets show, these devices are becoming a very popular topic. Moreover, this applies not only to romantics and treasure hunters, but also to quite presentable and wealthy people. Some of them see an opportunity to make money, others are simply carried away by the process in the hope of finding a rare or unique item. This kind of “hunting” can be compared to fishing, in which people are also attracted by the intrigue of expecting an unsurpassed catch.

Description

It is worth noting that search magnets, reviews of which are presented in the article, come in two varieties: single-sided and double-sided. They differ from each other in the number of working edges. In the first case, to fix the element, a standard fastening is used in the form of an eye bolt, screwed into the central part of the plane in the non-working area. The second option is to weld the rope clamp to the body.

In double-sided devices, the fastening bolts can be screwed into the “edge” (side surface). This modification definitely has advantages; therefore, its cost is higher. The single-sided version can only be used for vertical lowering.

The optimal areas for work are from a bridge, a boat or in old wells. Many searchers throw the tool from the shoreline, and only the double-sided version is suitable for this purpose. The working washer falls face down to the bottom, after which the device is guided along the bottom using a cable.

A model with one active side is ineffective with this method of operation.

Double-sided search magnets became widely available not so long ago, and their prices have dropped significantly. The introduction of innovative technologies has made it possible to reduce the cost of the production process of elements. Since devices differ in size, cost and attraction efficiency, it is not so easy for a beginner to choose a suitable model, taking into account the features of its further use.

As already indicated, magnets are divided into two types of execution. When choosing a search analogue, you should take into account several more nuances and characteristics.

Regardless of the region of study and the final goal, reviews of search magnets indicate that they must have an attraction of at least 100 kilograms. It's not as much as it might seem.

The fact is that a device designed for 100 kg is capable of holding the specified weight under ideal conditions. For example, lifting a smooth metal part strictly vertically upward.

Peculiarities

If during operation you slightly change the angle of application of force, the device moves off the surface. Thus, even a 400 kg search magnet is capable of dragging no more than half of the calculated mass along the bottom. Considering that there is a lot of algae, sand and other foreign objects at the bottom of the reservoir, the unit can actually be pulled out 10 times less in weight.

You also need to remember the intensity and strength of the current. When the object comes off the bottom, it vibrates and breaks off if the water pressure is strong enough. In this regard, experts recommend using devices with a force of 200–400 kg to search for metal “artifacts.”

If a magnet is used to search for scrap metal, regardless of its historical value, the tool force must be at least 600 kg.

Although such a unit itself weighs more than a kilogram, it is capable of “fishing out” mountains of scrap metal, including the remains of vehicles and aircraft.

Accessories

Those who decide to mine certain finds will need to equip the search magnet with a special cable. You should not save in this direction, because the specified equipment will not cost much, and the loss of even a budget modification will not cause pleasant emotions.

As a rule, climbing ropes and their analogues are used as rope. Such devices are protected from abrasion and have a strong middle core, which prevents the rope from breaking at the most inopportune moment.

The length of the rope is chosen according to personal preference; usually it does not exceed 20 meters.

It is unlikely that it will be possible to physically throw a fairly heavy blank, even for a well-trained person. You will also need to purchase gloves made of durable material, since it is easy to get injured on elements of equipment and the findings. In addition, a special bag for the “catch” will not hurt.

Metal products lifted from the bottom are often corroded by rust, covered with algae, and have a rather unpleasant odor. In this regard, transporting them in a bag or a regular backpack is impractical.

Another point worth paying attention to is tying the rope with a simple but reliable knot.

Maintenance and care

A high-quality double-sided search magnet does not require special care. The materials used to manufacture such a device are alloys of iron, boron, neodymium with a stainless coating. It is housed in a housing with anti-corrosion coating. The essence of care is wiping the element with a dry rag, clearing it of metal shavings that collect in hard-to-reach places, of which there are not many.

The device itself is durable and reliable. The loss of power parameter is no more than one percent in 10 years. The magnet must not be subjected to shock or thermal heating.

For example, 80 degrees is enough to completely neutralize the properties of the tool, after which it turns into an ordinary blank.

If searches are accompanied by video recordings, it should be taken into account that magnetic waves negatively affect all electronic devices, including mobile phones and tablets. After each use, it is necessary to check the integrity of the rope and the reliability of the knot.

What and where do they find it?

Reviews of search magnets clearly state that precious and non-ferrous metals cannot be found with its help, since they are not magnetic. Consequently, only iron and some alloys can be found. Often, “pathfinders” find keys, locks, coins, knives and other “trifles.” Among antiques, horseshoes, ancient tools, and forged items are most valued.

Search engines often come across ammunition and weapons, both from the Second World War and the dashing 90s. It’s better not to mess around with such “belongings” by returning them or calling the appropriate special services.

Regardless of the purpose of the search (scrap metal, artifacts, or all together), the best “catch” will be in crowded areas. It turns out that good places include pedestrian and automobile bridges. Most often, this is where citizens lose or deliberately throw away valuables and other items.

In the area of ​​ancient crossings, the likelihood of finding valuables is higher than near modern structures.

Search magnet “Supersila”

Devices under this brand are produced by the Moscow NPK Supersystem. The assortment includes options that differ in operating principle, material of manufacture, and load capacity.

One of the most popular modifications is the F-300 version. The design includes a neodymium working part and a steel frame. The body is equipped with a threaded through hole, which serves for convenient pressing of the element from the iron surface through an eye bolt, which is included in the kit along with the nut.

Search magnets "Supersila" are designed to identify and lift steel objects from reservoirs, caves, wells, and excavations. Judging by the reviews, this design is suitable for searching for scrap metal. The lifting force under optimal conditions is several hundred kilograms. The device in question pays for itself in several trips, even if you only search for ferrous metal. The F-300 model is capable of holding up to 420 kilograms, the body coating is zinc, the weight of the device is 1.9 kg.

These devices are popular with tens of thousands of search engines in many countries. The advantages of the unit include the compliance of the specified power with the declared characteristics, unlike most Chinese analogues. The design of the best search magnets is standard:

• metal body in the form of a bowl;
• working part made of neodymium;
• eye bolt with nut.

The introduction of iron and boron impurities makes it possible to enhance the properties of the unit and give it additional strength. The working element is securely mounted in a steel cup using epoxy resin, and the protective anti-corrosion coating is zinc-coated.

A mandatory structural part includes an eye bolt, oriented to separate the magnet from the metal object. In addition, the specified screw serves to secure the cable. The part is mounted in a special through hole.

The purpose of one- and two-sided search magnets “Triton”:

• protection of wells and reservoirs from iron-containing inclusions;
• search for archaeological, historical and valuable artifacts;
• checking sand or soil for the presence of metal objects;
• scrap metal sorting;
• search for lost objects on beaches and in reservoirs.

Magnets from the Nepra company

The Nepra company has been producing various search equipment since 2009. The profile direction is search single- and double-sided magnets and related equipment. Single elements have a simple design and are optimally suited for work in mines, wells and swamps. Versions with two working edges are designed for manipulation from a boat and the coastal zone of various bodies of water.

The table below shows the comparative parameters of some types of Nepra search magnets.

F-600	—	600	2,28	nickel	—	125	160/145/125

Safety

Since a double-sided search magnet belongs to the category of high-risk tools, certain rules must be followed during its operation and storage:

1. It is forbidden to place fingers or other body parts between the metal and the magnet. This can lead to soft tissue injury.
2. To avoid damage to electronic devices (watches, phones and other gadgets), you should keep them at a distance of at least 250 millimeters from the working device.
3. When heated above 80 degrees, the unit completely loses its properties.
4. The magnet is transported in wooden boxes with a wall thickness of 10 mm on the sides and 20 mm on the bottom.
5. The natural loss of performance is 1–3 percent over 10 years.
6. The device is stored in a special case or packaging with thickened walls and a bottom covered with foam, rubber, and boards.

Price

Many consumers are interested in the question, how much does a search magnet cost? Its price depends on the model configuration, equipment and manufacturer. A two-section new device will cost from 2.5–3 thousand rubles.

Search magnet: what is it and how to use it?

To answer the question of how to use a search magnet and do it correctly, it is important to correctly assess the specifics of the materials from which this product is made. It is based on a rare-earth supermagnet based on a neodymium-iron-boron alloy.

This compact product can attract and securely hold metal objects whose weight is tens of times greater than its own mass. Thanks to their high power, search magnets successfully lift objects of impressive size from the bottom of wells, lakes and rivers.

They can be used to quickly and easily check large littered areas for metal objects (including scrap metal). 

Limitations when using search magnets

In order for a search magnet to serve you for as long as possible and allow you to discover many interesting finds, you should remember its weaknesses:    

 1) High temperatures. Neodymium alloy is extremely susceptible to high temperatures. Use at +80⁰C is almost guaranteed to lead to loss of its magnetic properties. The optimal temperature for using the product is –50..+50⁰C.      

2) Moisture. The galvanized body of the search magnet reliably protects the neodymium alloy. The shell may cease to cope with its main function if there is serious damage, which can be caused, among other things, by poor cleaning of rust after using the product. The unprotected powder base of a neodymium magnet rusts in normal humidity, so the integrity of the body is a prerequisite for long and reliable service of the product.

Basic precautions when using search magnets

To ensure that working with a search magnet brings only positive emotions and impressions, you must remember to follow basic safety measures:    

1. Protective gloves. During search operations, small sharp fragments of iron and rust are inevitably found at the bottom of reservoirs or in littered areas. Be careful when cleaning the surface of the product. Thick protective gloves are a must.      
2. Take care of your fingers. The attractive force of the most powerful models of search magnets reaches 600-800 kg. Never allow parts of your body to come between a heavy metal object and the working surface of the product.    
3. Use the magnet correctly. To lift the product from a large object, do not forget to use an eye bolt. When working, always hold the search magnet strictly by the mount.

What interferes with magnets at the bottom of reservoirs?

In order to imagine what a search magnet experiences under real operating conditions, you should look at the bottom of a reservoir, armed with a diving suit. Here you can find metal objects covered with many years of rust and covered with silt.

Naturally, in such conditions the magnet will not work at full strength. Most likely, the adhesion force will drop below one hundred kilograms. It’s a completely different matter if you are looking for a recently drowned object that has not yet become covered with silt, sand and rust - it is quite easy to pull out such a find.

As for objects that have lain at the bottom for several decades, the magnet can easily fall off them.

Search magnets are the treasure hunter's best assistant

Despite the emergence of multifunctional metal detectors, the most accessible and universal means of searching for metal objects remains a magnet.

In everyday life, it is indispensable for finding lost needles, nails or keys, and in nature, search magnets allow you to find real rarities and treasures in sand, soil, crevices and even in reservoirs. Moreover, they can work perfectly in tandem with metal detectors.

If you first examine an area of ​​the ground using a magnet, you can clear the area of ​​metal objects lying on the surface and simplify the task for the operator.

Neodymium magnets are the most powerful

The best results in your search can be achieved with neodymium magnets, which are widely available on sale. They are capable of not only detecting valuable finds, but also holding metal objects weighing several hundred kilograms! This is a fundamental advantage when you need to lift a heavy object to the surface from the bottom of a well, pond or deep ravine.

Magnets can be single-sided or double-sided. Single-sided ones are lighter, they are quite suitable for searching for treasure in the ground or in a small pond, and double-sided ones can attract objects from both sides, which is very convenient when working in crevices or over a large area.

Accordingly, the choice of certain magnets should be determined by the main purpose and conditions of their use.

What does a magnet consist of?

Search magnets usually have a round shape. Models of different diameters are available. They are galvanized and then glued into the housing using epoxy glue, which fills the gap between the housing and the magnet. The set of modern search magnets includes an eye bolt.

Neodymium magnets are made from a unique three-component alloy NdFeB (Nd - neodymium, Fe - iron, B - boron). Due to this combination, they acquire enhanced magnetic properties, surpassing all currently existing magnets. Their tearing force (holding weight) ranges from 40 to 600 kg or more, and this parameter is the most important when choosing neodymium magnets. Naturally, the greater the tearing force, the more powerful, heavier and more expensive the magnet.

The housing is a steel piece that contains a magnet. Thanks to the galvanized coating, the housing is resistant to corrosion and the magnet can be used in fresh and salt water. There are also cheap search magnets without a housing.

An eye bolt is used to attach a magnet to a cable or fishing line, for which a threaded hole is provided. For single-sided magnets it is located directly in the center, and for double-sided magnets it is located on the side of the body. Before using the magnet, the eyebolt is screwed tightly into the hole, after which the cable is attached to it. The rope must be very strong in order to be able to pull out the magnet along with the detected object.

How to choose a search magnet?

As already mentioned, the key characteristic of magnets is the pull-out force, denoted by the letter F. If you plan to use search magnets only in everyday life or to search for objects on the surface of the earth, then neodymium magnets F80-F120 will do this perfectly. With their help, you can pull out a tool that has fallen into the water (for example, scissors), as well as find lost keys.

To detect objects in soil or sand, you will need F170-200 magnets, and to find treasure in water bodies, you will need neodymium magnets with a pullout force of more than 200 kg.

In all of these cases, it is better to choose more powerful magnets, since the indicated maximum magnetization force is relevant only for ideal conditions. Any contamination, corrosion and irregularities somehow reduce this indicator.

The most powerful magnets (up to 500 and above) are rarely used due to their heavy weight and high price. The optimal magnet weight for long-term searches is no more than 1.20-1.40 kg.

What can you find with a search magnet?

Using a search magnet, you can find any metal objects: from ancient coins to weapons from times of war. It all depends on the power of the magnet and the location of the search (land, pond, attic). Among the interesting finds are jewelry and various utensils: metal utensils, spoons, knives, locks.

The most effective searches are in reservoirs and abandoned wells. There is even a whole clan of treasure hunters who prefer to search for rarities in the water. Double-sided neodymium magnets, which are easier to drag along the bottom, are best suited for these purposes. With the help of such products, amateurs can successfully catch coins from city fountains, where tourists generously throw them.

Of course, not every trip to nature pleases even experienced treasure hunters with valuable finds. But if you were unable to find rarities that would be of interest to collectors, then you can hand over the collected scrap metal and receive financial compensation for your time spent.

According to treasure hunters, there are “fruitful” days when you can collect a lot of scrap metal. If the magnet is not very powerful, then you can simply walk along the beach or other vacation spots and find modern coins, keychains and other small items.

Naturally, it is better to use neodymium magnets, since their use significantly increases the likelihood of detecting both ordinary metal objects and interesting finds.

Neodymium magnets are not only the most powerful, but also very durable. If you do not use them at extreme temperatures (over +80 °C), then in ten years they will practically not lose their magnetic properties.

However, it should be noted that working with powerful magnets requires compliance with certain rules. First of all, it is advisable to use gloves and safety glasses. Do not carry the magnet together with bank cards, flash drives and phones to avoid damage or demagnetization.

Small children and people with pacemakers should not use magnets.

Search with neodymium magnet

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. Search magnets 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.

Something about the search magnet

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 - a neodymium search magnet. 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.

Of course, a cop with a magnet is inferior to a search with a metal detector, but, as they say, who is looking for what? Therefore, I will not strongly recommend it, but if you really want to look, then you can try.

Scrap metal extraction from water

Mining and selling scrap metal is a fairly common hobby today that can bring serious income.

Typically, the search for scrap metal is carried out in old fields, near factories, abandoned villages, landfills and many other places. The competition here is quite strong, so it is difficult to hope for serious production. However, when all the land has been explored, water remains!

Yes, many search engines eventually begin to pay attention to water. Of course, extracting scrap metal from water is much more difficult and requires having special equipment on hand. However, as a result, the costs are well worth it with interesting finds.

We climb to the depths

If you are interested in searching specifically from the depths of rivers, lakes and reservoirs, then you will need not an ordinary metal detector, but a special underwater metal detector or a powerful search magnet. And, of course, a boat that allows you to explore the maximum area. In this case, the extraction of scrap metal from water becomes more efficient.

Searching from a boat is simple - the search magnet is tied with a fairly strong (preferably thin, but VERY strong) rope and thrown overboard, after which the person sits on the oars and rows in an arbitrary direction. Any objects from the bottom, be it sunken fittings, a watch, a knife, a bicycle frame or a caterpillar track, cling to the magnet. All you have to do is check your catch from time to time by pulling out the magnet and removing the catch.

searching in boats using a search magnet:

The cost of magnets varies greatly. Some models can be purchased for 800 rubles, while others can cost up to 10 thousand rubles. First of all, it depends on the power. The more expensive the magnet, the more powerful it is. The weakest ones have a clutch capacity of 80-100 kilograms. The grip of the most expensive ones can reach up to 600-800 kilograms. But most search engines prefer to find a compromise by purchasing search magnets with a clutch from 150 to 250 kilograms.

Finding scrap metal with a search magnet

You should be very careful when choosing a clutch. Keep in mind that the number indicated in the characteristics simply demonstrates the power of the magnet, and does not indicate its exact value.

After all, if the magnet’s adhesion is 100 kg, then it is able to demonstrate it in perfectly clear water, being close to a large object that is not hidden by a layer of silt.

He most likely will not be able to get the same object in muddy water, and even if it is hidden by a layer of sand or silt. Therefore, it is better to take with a reserve.

Search magnets can vary not only in cost, but also in design. Single-sided and double-sided models are available on sale. The first ones have one ring - on top. The second two are on top and on the side. The latter are noticeably more expensive, but they are more convenient to use as a trawl - drag the magnet along with you and be sure that any metal objects capable of magnetism that get in its way will become your prey.

Use a magnet on the bridge

Some people, without a boat, prefer to use magnets on bridges, crossings and piers. This is also an interesting solution. It is enough to stock up on a long rope, throw the magnet off the bridge and drag it several tens of meters along the bottom. After all, people on a bridge can drop a variety of things into the water.

And if this bridge has stood in one place for several decades (and maybe even replaced several other, old ones that stood here for a century or two), then the number of finds will increase significantly. Of course, when searching, you should exercise extreme caution so as not to jeopardize your life or health.

But still, this is quite an exciting activity that will definitely captivate you.

metal search with a search magnet at the crossing:

Looking on beaches near the water

Beach searching is quite popular. Some searchers limit themselves to jewelry and coins, but such searches are not always successful, and competition in this area is very high. Finding scrap metal on the beach, on the other hand, may be less lucrative, but is almost always satisfying. To do this, use a metal detector suitable for working in water. They travel with it both along the surf and at shallow depths near the shore.

Finding scrap metal on the beach

Metal objects that fall into the water (especially in lakes and freshwater reservoirs) can lie in the water for many months and even years, but gradually the waves push them closer to the shore. Sand and silt can hide them, so thousands of people can walk by and not notice. But if you have a metal detector at hand, you probably won’t return home without interesting finds.

If we are talking about scrap ferrous metals, then it is worth looking on Soviet beaches, especially those that were near a boat station, fishermen’s parking lot or a concentration of water equipment.

What can you find on the beach

On such beaches (especially at low tide, if we are talking about the sea or a reservoir) you can easily find anchors, old anchor chains, spare parts and body parts of ships.

Old anchor on the beach

Searching for scrap metal on the beach will be complicated by signals from small targets - corks, beer cans, can ears, etc. Therefore, if you are going to look exclusively for black scrap metal, then you should reduce the sensitivity of the device and turn off the colored signals.

On some remote and inaccessible beaches you can even find a long-forgotten car. Also a good find, plus 500-600 kilograms of ferrous metal to your loot.

Industrial extraction of scrap metal from water

If we talk about large volumes of metal and the extraction of sunken ships, pipes, and metal structures, then we are talking about industrial mining.

For example, there are companies that pull out entire pipelines from city rivers that need to be replaced or dismantled. They also raise sunken ships to the surface - barges, boats, etc.

For such work, special equipment is required - a powerful winch with an electric motor and gearbox, cables, and specially trained people.

If scrap metal is pulled out of the river, then the work is carried out on the shore. When pulling a pipeline out of the water, one end of it is attached to a cable and tension is applied. after that, on the other bank, the second end of the pipeline is cut off - it begins to float freely with the flow and at this time the winch gradually drags the pipes to the shore, where part is cut off, the cable is re-attached and so it sits until the entire branch is pulled out.

The pipeline passes through the river

Vessels are retrieved in the same way, usually from the shore.

How to choose a search magnet - TOP tips for treasure hunters

After reading this article, you will learn the main advantages of search magnets in comparison with pinpointers, familiarize yourself with the rules for using neodymium search magnets and make sure that buying a search magnet is a profitable investment. Extraordinary places to search will also be indicated. A search magnet, even if not very powerful, is an indispensable thing for a treasure hunter.

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, because by investing in a 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.

How to choose a search magnet?

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 would be the best solution to 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.

A promising investment and some tips

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.

Search magnet for gold and silver: what is it, does it exist, what metals does it attract, operating principle and assembly

We are glad to welcome you to our website, dear guests. Today we will talk about whether there is a search magnet for gold and silver, the principle of operation of the magnet, useful properties and methods of application. We will review the models and suggest a way to build such a device yourself. Stay, it will be interesting.

Magnetic field and metals that conduct it

A magnetic field is a force that can influence electric charges, atomic nuclei, and simplest particles. This is matter that arises from the interaction of particles that have their own charge. All substances react to this field, and some emit it.

Depending on the reaction, the substances are distinguished:

1. Ferromagnetic materials react to fields and retain magnetization. Thus, they themselves begin to emit their own field.
2. Paramagnetic materials - the electrons in their composition react to a magnetic field so weakly that such a reaction can only be detected using special measurements. Such substances include platinum, aluminum, oxygen.
3. Diamagnets are substances that do not attract, but, on the contrary, repel from a magnet, exhibiting negative susceptibility. Diamagnets include copper, water, carbon, gold, and silver. Most substances known to science are diamagnetic.

Design and types

Finders take advantage of the ability of some metals to interact with a strong magnetic field by using special search magnets in their searches. More often this is a simple design that contains the rare earth metal neodymium, enclosed in a steel case.

Depending on the scope of application, devices are produced:

• in the form of a rod for simplified access to narrow crevices and other hard-to-reach places;
• trawls that allow you to effectively examine the bottom of water bodies;
• one-sided, designed for lifting objects, equipped with a housing that shields magnetic radiation, providing one working surface;
• double-sided, suitable for universal work.

Principle of operation

A neodymium magnet forms a field that allows it to attract objects that exceed the weight of the search device by tens of times, depending on its size and power. This device works great both in air and under water.

Working with the device is simple - just attach it to a rope and lower it to where the item you are looking for is supposed to be located. Under the influence of a magnetic field, metal objects “stick” to the device and can be removed to the surface.

Differences from a metal detector

The operating principle of a metal detector is also based on electromagnetic radiation, however, this device does not attract metals to itself, but captures echoes of the “response” of substances to the field it emits. If there is metal in the ground or water, the device gives a signal. Further work on retrieving objects falls on the person.

The magnet does not provide any information, but simply “attracts” to itself those objects that it is capable of influencing.

Where can it be used

There are areas where you cannot do without a device:

• deep wells;
• rock crevices;
• the bottom of reservoirs, including at great depths.

The device allows you to explore such places and remove objects located there without additional effort.

Can you attract silver and gold?

Precious metals are diamagnetic, so they cannot be extracted using a magnet. An exception may be objects that contain parts made of ferromagnetic metals, and such a part must be voluminous enough to be attracted.

You should not rely on the device to magnetize precious alloys. As a rule, the proportion of ferromagnets in the composition of the alloy is extremely small.

If you want to search only for precious metals, you are better off purchasing a metal detector.

What metals still attracts

The most famous ferromagnets:

• among metals - iron, cobalt, nickel, chromium;
• their alloys, such as cast iron and stainless steel.

Rare earth metals (lanthanides) are attracted to the device. Manganese, sulfides, selenides and tellurides have ferromagnetic properties.

Advantages and disadvantages

The indisputable advantage of a magnet is its ease of use:

• it does not require special storage conditions; you should, perhaps, avoid heating it above 80 degrees;
• does not need recharging;
• has a very simple design;
• takes up little space.

The disadvantage is that it cannot be used to extract gold, silver, and their alloys, including nuggets.

Another thing is metal detectors. The advantage of modern metal detectors is their ability not only to find, but also to distinguish which metal is within its coverage area. How does this feature work? This was made possible thanks to the use of a computer in the design of the device, which analyzes all incoming signals, reacting to the smallest changes.

Is it possible to make money searching for gold and silver with a magnet?

It is impossible to effectively search for precious metals using only a magnet. However, you can use it as an additional device, along with other equipment.

Using it, you can clear the surface of the search site from metal debris, which usually makes it very difficult to detect silver and gold with a metal detector.

Tips for choosing

In addition to their shape, the devices also differ in the strength of the radiation and the method of attaching the cable.

Experienced treasure hunters are advised to choose powerful double-sided magnets, since they are universal and easy to use, although they are more expensive.

Weight and ammunition

Any tool is most effective if it is selected in accordance with the task at hand. The choice of magnet is no exception. To begin with, you should decide what items it will be used to search for, and based on this, select the appropriate device.

It should be taken into account that the higher the power of the magnet, the greater its mass and cost. The optimal option is 400 kilograms. This is not the weight of the magnet, but the weight it can lift!

In addition to the magnet itself, you will need a cable with which the search device can be lowered to the bottom of the reservoir. It is better to choose ammunition with a large margin of safety, exceeding the power of the magnet itself, in order to avoid ruptures and loss of the device. Finding him later is almost impossible.

Review of popular devices and their prices

The most well-known magnet manufacturers offer devices of varying power and cost:

1. NPK Supersystem produces a wide range of magnets. A device capable of lifting a weight of about 90 kg will cost about 700 rubles. For a very powerful double-sided copy, designed for 690 kg, you will have to pay more than 7,000 rubles.
2. CJSC NPO Redmag produces magnets with a capacity of 600 kg and a cost of 3-5.5 thousand rubles.
3. Magnets made in China are also very popular. A device with a capacity of 600 kg can be purchased for 4900 rubles, devices with a capacity of 300 kg are sold at a price of 2700-2800 rubles.

How to assemble and set up a magnet with your own hands

Making a magnet at home is not an easy task if you don't have neodymium supplies on hand. But building an electromagnet using not a rare ferromagnet, but an electric field, is quite simple.

Required Components

To build an electromagnet you will need:

• iron for the core (nail, lock shackle);
• copper insulated wire;
• source of electric current (battery, accumulator);
• connecting wire;
• soldering iron

Assembly sequence

Copper wire is wound tightly, neatly, in one direction, onto the core. If a regular AA battery is used as the power source, you can connect it directly to the ends of the winding. For power supplies and batteries, it is necessary to solder the connecting wires (twisting and insulation are also allowed).

See the assembly visually in the video:

How to use it correctly

To search for valuables, it is better to use industrially made magnets. When purchasing a device, it is better to choose units with an eye bolt, which makes it much easier to separate the magnet from the object.

Safety precautions and what to be careful with

It should be remembered that the magnet affects all objects nearby, including pacemakers.

For a person who has such a stimulator, the magnet is dangerous, as it can cause malfunctions in the operation of the medical device.

Mobile devices and bank cards should also be protected from electromagnetic influence to avoid their failure.

How to distinguish a counterfeit coin from an original using a search magnet

If a coin is stuck to the device, you can be sure that it does not contain either gold or silver. A precious coin or jewelry will remain in its place when exposed to the device.

Tips for caring for your device

If work was carried out in water, after use the device must be thoroughly wiped from moisture and dried to avoid rust.

Protect the device from strong shocks, since neodymium cores are quite fragile, and if a crack or chip occurs, they lose power.

Reviews

Egor: “The magnet is great for removing small metal debris from soil dumps when working at a mine. I recommend".

Andrey: “It’s a great thing to get change out of fountains, especially in Europe.”

Victor: “Such a thing is of little use when searching for gold and silver, but for diggers who hunt in battlefields and look for artifacts of the Great Patriotic War, it is an irreplaceable thing.”

Conclusion

I hope this material has helped you clarify the question of what is the use of a magnet and whether it is worth acquiring such a device to search for valuable items.

Don't forget to comment on what you read and share articles on social networks. And we take our leave, all the best.

Search magnet for gold and silver and its properties

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.

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
• copper
• tin
• brass
• lead

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:

1. ferromagnets

2. paramagnets

3. 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.

How to store a search magnet?

A search magnet is a unique thing necessary for expeditions and search work. You can buy it at any specialized store that sells clothing and equipment for outdoor activities, sports and professional activities.

A magnet for this purpose is made using a hard alloy of iron, boron and neodymium. This combination provides the product with excellent performance properties and increases the force of attraction of the metal.

Today, search magnets are widely used in many areas and everyday life. It is required:

• to search for objects at depth: in wells, rivers and lakes;
• to check reservoirs for the presence of large metal objects - ships, planes, tanks and cars;
• for quick and effective cleaning of the area from metal debris;
• to prepare an area with loose soil before working with a metal detector;
• for searching for meteorite fragments;
• for private pickling of areas for the presence of ferrous metal scrap.

Requirements for storage and use of neodymium magnet

Search magnets can be dangerous to humans, so users of such a device must follow a number of operating rules:

• It is recommended to store and transport the product in a wooden box with wide walls. This will help avoid negative effects on humans and mechanical damage to surrounding objects;
• if small metal products are attracted to the device, then in order to avoid cuts and injury, it is necessary to remove them using gloves;
• Use the magnet carefully and carefully. Avoid possible exposure of lower or upper limbs to the gravity field;
• the distance between the search object and electronic accessories must be at least 10 cm. Failure to comply with the requirements may disrupt the operation of phones, laptops, tablets and other devices;
• The magnet should be stored away from water or electricity meters, and chains, cables and other steel parts should not be brought close to the product;
• operation of the equipment is possible only at temperatures from -50 to +50 °C;
• If the temperature conditions are not observed, the equipment may lose its magnetic properties.

Professionals and amateurs should remember that over 10 years of service, a search magnet loses about 2% of its magnetic properties.

Search for coins and treasures

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

In this article I will tell you: which coins can be magnetic and which cannot? what types of magnets are there? how to search with a search magnet? What can you find with a magnet, and in what places can you find something worth 100%?

Anyone who has decided to sell the found ferrous metal is advised to read our article.

What metals does the “search magnet” attract?

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

For 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 may be in an iron case-box (according to statistics, all the treasures found were located there), secondly where have you seen coins made from the same metal?

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

Precious metals are a different matter, and gold and silver are fused reluctantly, one might even say not at all.

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

The higher the magnetic properties of a coin, the more iron or other ferromagnetic there is in the copper alloy (well, at least 1.0–2%).

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

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

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

I advise you to have a very strong magnet (preferably made of non-bium) to search for coins.

What types of search magnets are there? Where can I 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” 5800 rubles.

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

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

Safety precautions when working with a magnet are very important: do not insert any parts of your body between the magnet and the metal, as you can be seriously injured (in some cases, even fractures); when transporting, make sure that it does not come into contact with metal parts of the machine, do not heat the magnet, as at temperatures above 80 degrees Celsius, it can 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 small change (modern 10 rubles are especially well magnetized), keys, corks, etc.

When searching in the attic, we advise you to comb the area first with a magnet so as not to rush into hundreds of metal detector signals; there are a lot of metal objects there.

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

Usually there is sandy soil, a convenient descent, and a flat shore area.

Also, if you live in 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 ancient and abandoned).

Also, don’t forget the tradition of throwing coins into the sea on vacation so that you can come back again, or into the river “for good luck.”

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

By the way, if you sell 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.

Yes, move electronic devices away from the magnet, as it can strongly influence them with its magnetic field.

Good luck with your “catch”. Read our blog

Types and uses of search magnets for gold and silver – Glitter Gem

Many companies offer to buy a search magnet for gold and silver. Every person at least once in his life dreamed of finding a treasure. We need to figure out whether it is possible to attract precious metals to a regular magnet?

Search magnets

To lift ferromagnetic metals and alloys from the bottom of rivers, ponds and wells, magnets F 200 – F 400 are used (depending on the difficulty of access and the size of the load).

Even if they are the same size, the tearing force can be different, it depends on the content of neodymium (a chemical element). The more neodymium, the more powerful the magnet. For one person, a model with a diameter of up to 1 m and a lifting force of up to 300 kg will be optimal.

It is important to know that flat objects attract better than round ones.

Safety precautions or what to be careful with

When using a magnet, you must adhere to certain rules:

1. Neodymium should not be heated above 80°C.
2. The magnet affects the magnetic fields of electrical devices, pacemakers, watches, credit cards.
3. The large device is stored and transported in a non-magnetic, for example, plastic container.
4. You cannot stand between a large magnet and an iron barrel/door, etc., it will be attracted, and a fracture of an arm/leg or other part of the body may occur.
5. Wipe the device after each use, clean it from dirt, do not leave it without a case, and it will serve you for many years, since the device does not break down and does not require repair!

Have an easy search, precious finds and more gold!

Search magnets for gold and silver: operating principle, review of models and prices

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.

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.
