Search magnets for gold

Under search magnet it is necessary to understand a certain device with which you can find places of magnetic radiation that come from objects made of various metal alloys. A magnetic field is formed by electrons emitting moving electric charges. Strong magnets are used to search for precious metals, including gold or silver. But since Since precious metals do not respond to magnetic fields, special devices are used to detect them, which include a neodymium chemical element. These search magnets are called neodymium.

Neodymium magnet - This is a device that attracts various objects made of metal. It is able to grab and stretch objects whose weight can exceed its own mass tens of times. This is a fairly powerful search appliance, incorporating neodymium, iron, boron. The components of the magnet are housed in a steel casing, most often having a flat round shape.

To retrieve the items found was convenient, the design of the search engine is equipped with with a bolt which is screwed into the housing using a threaded connection. Attach to this fastener strong rope or cable - with their help it is possible to raise a magnetized object even from the depths of the water basin.

Any precious metals (including gold) have in their composition a certain composition of the ligature, which makes the material hard and ductile. Alloys contain ferromagnetic components that are attracted to a neodymium device. This is how jewelry is detected and brought to the surface.

Neodymium search engine is available in several varieties. Such devices may be applicable in everyday life, when solving search problems in private, research or industrial purposes. Options neodymium devices can vary from each other in power and size.

Depending on what the neodymium magnets are for, they are divided into 4 types.

• Bar magnets. They are distinguished by a narrow design, designed to work in hard-to-reach places or narrow crevices.
• Search trawls. Magnets used to inspect the bottom of rivers, lakes or other bodies of water.
• Single sided magnets. They have only one working surface, with the help of which metal objects are detected and they are lifted.
• Double sided magnets. They have two work surfaces, which is why this device is considered universal.

Devices with one working surface are used for search work on the surface of the soil. In the case when it is required to search for metal objects at the bottom of a reservoir, it is more expedient to use a structure having two work surfaces. If long and large-scale work is ahead on a large surface area hidden under the water column, magnet trawl. With the help of such a device, it is possible to attract objects from a large distance and a significant mass.

Any neodymium search engine containing iron is exposed to the action over time. corrosive processes, because of which the strength of its magnetic field is gradually reduced.

Neodymium magnets are considered the strongest if their Compare with other analogues. When several magnets are connected to each other, the strength of their magnetic field increases, but only by 30%, and each pole of the magnet has an equivalent attractive force. The force of attraction of a neodymium device is affected by the ambient temperature.

Gold Neodymium Magnet is a fairly sensitive and powerful device, which is able to detect even a small amount of impurities contained in a gold alloy. He is magnetized not only on precious metals, but also takes any others that are in the field of his action.

Neodymium devices began to be used to search for precious alloys due to the fact that the rare earth metal neodymium that is part of this magnet is known as a compound with a magnetization function and resistance to demagnetization. In addition, this element is used in the manufacture of particularly powerful magnetic devices and devices that are able to respond to ferromagnetic components located at a great distance from the magnet.

The neodymium search engine catches items from gold or silver due to impurities in them of other metals that make up the ligature. And although the amount of impurities in the composition of a gold product or alloy can be very small, sensitive neodymium will still detect the ferromagnetic components of the ligature in the alloy and magnetize them along with all other contents.

Pure - without any impurities - gold has a diamagnetism, that is, it is not attracted by the magnetic field of the magnet, but, on the contrary, is repelled, exhibiting negative susceptibility. It appears that a bar of pure gold cannot even detect a neodymium magnet. Pure gold can be found only with the help of a metal detector, the principle of which is not aimed at extracting metal objects, but at an alert about their presence in a certain range of the device.

Treasure hunting has always been a popular and interesting pastime. Modern seekers of precious metals use rather large and powerful double-sided neodymium magnets in their searches, since they are universal in work.

To pick up a search magnet, you need to determine in what conditions it is planned to be used. In addition to the magnet, you must purchase rope or strong rope - they are best chosen with a certain margin of safety, since no one can probably know what will have to be raised to the surface. The strength of the cable, as a rule, is chosen 2 times greater than that required for the working power of the magnet. This will save you from accidental clipping fasteners and the irretrievable loss of the search device.

The following manufacturers of neodymium magnets are most popular.

• Moscow Scientific and Production Company "Supersystem". Model of a one-sided magnet F-600 with a diameter of 130 mm. The power of separation is 660-690 kg, the cost is 4,500 rubles.
• Kaluga Scientific and Production Association "REDMAG". Releases a single-sided magnet F300 with a diameter of 94 mm. The power to break this option is 600 kg, the cost is 3000 rubles.
• Chinese-made magnets. For example, a model F400 with a diameter of 116 mm. The power of separation is 400 kg, the cost is 3,500 rubles.

When choosing a neodymium magnet to search for gold and silver, it should be remembered that the power of a magnet directly depends on how much mass it is able to lift to the surface.

Search neodymium devices have marking with the English letter F (Force - force) with a numerical designation that corresponds to the power of the device. If the search magnet is double-sided, then its designation will look, for example, like this: F400x2 (where the number 2 means that the model has two working surfaces). When choosing a device for searching for gold, it should be borne in mind that the power of a neodymium search engine will manifest itself in different ways in different conditions. Under ideal conditions, the new device can show power even higher than declared, but in practice, during operation, the attractive force will be slightly reduced. This is influenced not only by corrosion of the magnetic material, but also various contaminants that occur on the soil or at the bottom of the reservoir.

Besides, the contact area of ​​a neodymium search engine and a metal object depends on how smooth the surface of the object found. Powerful devices for searching for metal have a greater retention force than weaker models, so the number of so-called gatherings of found objects in small magnets will be significantly higher. Small neodymium devices (such as F150 and F200) are designed to search for small items - coins, rings, fishing lures. Medium models with capacities ranging from 250 to 800 kg will help to find objects that are large in weight and size, but it is difficult to work with them, since the mass of such neodymium devices is also large and it is quite physically difficult to throw them, for example, into water.

The choice of a neodymium magnet to search for precious metals depends on what objects by weight and size you want to detect. In addition, you need to focus on your physical abilities - Will the magnet work for you? And one more factor to consider - the more powerful the magnet, the greater its weight and cost. Therefore, the choice of model also depends on your financial capabilities.

According to the reviews of experienced search engines, the cost of a powerful magnet pays off much faster than the cost of low-power analogs. To do this, you have to carry out no more than 5 search outputs. The fact is that with a powerful magnet for 1 time you can collect much more various metal objects than you can do with a small neodymium device, even in a few exits.

Choosing a neodymium magnet to search for gold, you must also determine how many working sides it should have. One-sided search devices are used to detect metal in a well, near the surface of the soil. It is also convenient for casting from a bridge, pier or boat. If you want to throw a neodymium magnet from the shore, then in this case the two-sided option will be most effective. The same magnet can be used both from a boat and from a bridge - which is why it is considered universal among treasure hunters.
