The strongest magnet and magnet type

　　The strongest magnet:

　　At present, the magnet with the highest performance is a rare earth magnets, and in rare earth magnet, NdFeB magnets are the most powerful magnets. But in 200 degrees Celsius environment, smco magnets are the most powerful magnet, .

　　Magnet type:

　　Magnet should be called magnetic steel, which is now mainly divided into two categories, one is soft magnets, and the other kind is hard magnets.

　　Soft magnet includes silicon steel sheet and a soft magnetic core. Hard magnet includes AlNiCo magnets, SmCo magnets, NdFeB magnets, among which, the most expensive is SmCo magnets, the cheapest is ferrite magnets, the one with the highest performance is NdFeB magnets, but the one with the most stable performance and the best temperature coefficient is the Alnico magnets, users can choose the hard magnetic products according to different needs.
