Neodymium magnet, marking, manufacturing, application

Magnets are used in many areas of human life, including everyday life - they are found in almost all home appliances. Today, neodymium magnets are the most commonly used. They differ from ferrite ones by a higher (approximately 10 times greater) level of residual magnetization.

This material is an alloy:

• gland;
• boron;
• neodymium (a metal from the lanthanide group).

The last rare earth element is the main element in the composition. Boron is present in negligible quantities, and iron is a binding component.

Thanks to this composition, the necessary physical characteristics are achieved.

• Incredibly high adhesive force, which cannot be compared with the capabilities of ferrite magnets. For example, if connected ferrite rings can be difficult to disengage with your hands, then with neodymium rings everything is not so simple. It will not be possible to separate them without tools.
• High resistance to demagnetization. Every 10 years of operation, the material loses a negligible percentage of its beneficial properties (up to 2%). This factor has led to its use in the production of medical equipment.

Features of storage and operation

The service life of neodymium magnets with proper use is 30 years or more, but if handled carelessly they easily deteriorate.

The fact is that the material is not flexible at all. Under load it breaks and cracks. A fall or impact can lead to chips - the adhesion properties are reduced. A sufficiently strong impact can deprive the product of its magnetic properties even without visible damage. Therefore, falls and use in mechanisms with parts that come into contact during movement should be avoided.

Another extremely important point is that when the material is heated above the permissible value, the magnetic properties are irretrievably lost. It is almost impossible to process the finished product in any way or give it a different shape. Grinding, cutting or drilling may cause the alloy to catch fire. The thermal energy released during friction reduces the adhesion force.

If storage and operation are properly organized, the material loses only 1 to 2% of magnetization over 10 years.

The best search magnets – where they are used

A search magnet is a compact and powerful product that can attract and hold metal objects weighing tens of times its own weight. They are used to search and retrieve objects from wells, rivers and standing reservoirs.

Application of neodymium magnets

High adhesive force determines a wide range of applications for products. They are used in industry, everyday life, medicine and many other areas.

• The material is indispensable in the production of filter devices. Due to high magnetic indicators, the lion's share of metal impurities is retained on the surface.
• Magnets have found application in medicine. They are part of magnetic resonance imaging machines. These devices are used to relieve arthritis pain.
• The high level of magnetic energy of neodymium magnets is ideal for prospecting work. Metal detectors based on them do an excellent job. They are actively used by weapons and equipment restorers.
• Replacing old magnets in a generator or motor will significantly increase power. The engine will work better, the speed will increase, and energy consumption will decrease.
• Not long ago, this material found a place in the production of souvenirs and advertising stands.
• At the household level, magnets are used, for example, in plumbing fixtures, all kinds of appliances, or as souvenirs on the refrigerator.

Neodymium and its uses:

Neodymium, which is part of the alloy, is a chemical element located in the lanthanide group in the periodic table. It belongs to the rare earth metals. In addition to its use in the manufacture of powerful permanent magnets, it can be used as an additive to improve certain properties of structural alloys and steels, as well as for the manufacture of neodymium glasses, which use neodymium oxide, for the production of high-quality fiber optic light guides using neodymium fluoride, and for the production of thermoelectric materials using neodymium telluride.

Features of choice

First of all, you must determine for yourself what purposes the magnet will be used for. If you are keen on searching for various antiques in rivers and lakes, then you should pay attention to more powerful specimens. Medium-sized magnets can handle many everyday tasks, and small magnets are great for making magnetic buttons, fasteners and buttons on clothes, bags, furniture, and toys. Thus, you should choose a magnet according to the following characteristics:

• Form;

• Dimensions;
• Weight;
• Breakout force;
• Material code.

The material code indicates the magnetic strength of the product and the operating temperature range. N42 magnets are considered the best option today in terms of quality and price.
