Why are NdFeB magnets so popular in the computer and communication industries
March 07, 2022

Nd-Fe-B magnet is a kind of magnetic material widely used. Although the original magnetic materials came from nature, they have been applied to various industries with the improvement of science and technology, giving play to their potential value. They have played their divine power in electronics and military.

With the development of computer, communication and various electronic products, rare earth permanent magnet has been effectively applied, especially NdFeB permanent magnet industry has developed rapidly.

Rare earth permanent magnet material is the most stable and effective magnetic material at present. Its magnetic properties are more than 100 times higher than those of magnetic steel used in the 1990s, much better than those of ferrite and aluminum nickel cobalt, and twice as high as those of expensive platinum cobalt alloy. The use of rare earth permanent magnet materials not only promotes the miniaturization of permanent magnet devices, improves the performance of products, but also promotes the production of some special devices. Therefore, the emergence of rare earth permanent magnet materials immediately attracted great attention and developed very rapidly. Developed in China,the properties of various rare earth permanent magnet materials have approached or reached the international advanced level.

Rare earth permanent magnets are divided into samarium cobalt (SmCo) permanent magnets and neodymium iron boron (NdFeB) permanent magnets, and neodymium iron boron strong magnets have the title of magneto king, which is a rewarding title given by customers' experience in the process of use.

Rare earth permanent magnet materials have become important materials in electronic technology and communication. They are used in traveling wave tubes and circulators in artificial satellites and radar, as well as micro motors, micro recorders, aviation instruments, electronic watches, seismometers and other electronic instruments. The application of rare earth permanent magnet has penetrated into automobile, household appliances, electronic instruments, nuclear magnetic resonance imaging instrument, audio equipment, micro special motor, mobile phone and so on. In medical treatment, the use of rare earth permanent magnet materials for "magnetic acupoint therapy" has greatly improved the curative effect, thus promoting the rapid promotion of "magnetic acupoint therapy". Rare earth permanent magnet materials are one of the fastest developing fields in the application of rare earth. It not only brings great impetus to the development of rare earth industry, but also has a far-reaching impact on many related industries.
