Magnetic material classification

Magnetic materials are divided into two categories: metal and non-metal according to their properties. The former mainly include electrical steel, nickel-based alloys and rare earth alloys, and the latter are mainly ferrite materials. According to the use, it is divided into soft magnetic materials, permanent magnetic materials and functional magnetic materials. Functional magnetic materials mainly include magnetostrictive materials, magnetic recording materials, magnetoresistive materials, magnetic bubble materials, magneto-optical materials, gyromagnetic materials and magnetic film materials, etc. The basic magnetic properties of magnetic materials are reflected by magnetization curves and hysteresis loops. and magnetic loss, etc.
