Any substance in the external magnetic field can be magnetized, but according to the degree of magnetization and exhibits characteristics, material can be roughly divided into three categories: paramagnetic, diamagnetic and ferromagnetic. Paramagnetic and diamagnetic materials are commonly called weak magnetic material, and a ferromagnetic material is called a ferromagnetic material, commonly referred to as a magnetic material refers to a ferromagnetic material. According to different demagnetization difficulty after magnetization of the magnetic material is easy to be called a soft magnetic material, it will not be easy to demagnetization called permanent magnetic material. Soft magnetic material remanence weak,? Rare earth permanent magnet suppliers, and easy to demagnetization. Applications that require repetitive magnetization places, such as recorder heads, in computer memory components, switching power supplies, transformers and alternators, solenoids and various high-frequency components of the core and the like. Yong-strong magnetic remanence, and difficult demagnetization, made for permanent magnet? Rare earth permanent magnet used in the permanent magnet motor, magnetic separator, speakers, magnetic-electric instruments and other devices. Health magnet magnetic medical care purposes only have important applications in modern medicine, such as magnetic resonance imaging technology, often called MRI CT (computerized tomography), and MCG and MEG applications, and there is a long history. In the Western Han Dynasty "Historical Records" (about 90 BC) in the book "public warehouse Biography" will be referred to the king serve the medical use of five kinds of mineral drugs (called five stone) treatment. The five mineral medicine refers magnet (Fe3O4), cinnabar (HgS), realgar (As2O3), alunite (aluminum potassium sulfate) and Zeng Qing (2cuCo3). Then there are the ancient healing magnet application records. ? Rare earth permanent magnet magnetic new Xin Tong,?
