permanent magnets

Description

Rare earth permanent magnet materials, namely permanent magnet materials contain rare earth metals as alloying elements. Permanent magnet material refers to the magnetization after removing the external magnetic field and can maintain strong magnetism for a long time. Earth permanent magnet material has become an important material in electronic technology communication, used in artificial satellites, radar, traveling wave tubes, circulators and micro-motors, micro recorders, aviation instruments, electronic watches, seismometers and some other electronic instruments. The application of rare earth permanent magnets has penetrated into automobiles, household appliances, electronic instruments, nuclear magnetic resonance imagers, audio equipment, micro motors, mobile phones, and so on. In terms of medical treatment, the use of rare earth permanent magnet materials for "magnetic point therapy" has greatly improved the efficacy, thus promoting the rapid promotion of "magnetic point therapy". In the application of rare earth in various fields, rare earth permanent magnet material is one of the fastest development. It has not only brought a huge impetus to the development of the rare earth industry but also had a considerable impact on many related industries.
