One of the important parameters of permanent magnet materials is the stability of magnetism, which mainly refers to the influence of internal and external factors on the magnetic properties of permanent magnet materials after magnetization: temperature, time, chemical corrosion, mechanical vibration and shock, radiation, etc. The most significant impact on the stability of neodymium permanent magnet materials. The three parameters to measure magnetic performance are: remanence, coercivity, and maximum magnetic product energy. First, let's understand the concept of related parameters. Read More

Magnets that can maintain their magnetism for a long time are called permanent magnets. Such as natural magnets (magnetite) and artificial magnets (alnico). In addition to permanent magnets, there are electromagnets that require electricity to be magnetic. Permanent magnets are also called hard magn Read More
