The role of magnetic material in the production of modern industrial equipment is growing, according to the different properties of the magnetic material can be divided into magnetic and non-magnetic metal two categories, then what the differences between them?
　　First, the metal magnetic material, by definition, is a magnetic material made of a metal alloy or metal compound made. Most of the metal magnetic material is iron, nickel or cobalt-based, then add some other elements made of high-temperature preparation. Such magnetic material in many places play an important role, such as high temperature, low frequency, high power applications. In addition, the metal magnetic material can be divided into specific hard magnetic and soft magnetic pressure. Soft magnetic material is easily demagnetized, so much used in the manufacture of electromagnets, transformers and the like. Hard magnetic materials with strong magnetic, but not easy to be eliminated, so the hard magnetic material, also known as permanent magnet materials. Such materials are mainly used in the production of electrical devices. Magnetic pressure magnetic material can vary the length of the material changes shape, so with deep electric transducer machine is a good choice.
　　Non-metallic magnetic materials, is the use of non-metallic materials synthesis of magnetic material, ferrite highlights here. Ferrite by some baked mixed metal oxide, the production process is somewhat similar to ceramics. Ferrite has the characteristics of high permeability, high resistivity. The main use of the occasion is the electronic technology of the antenna and the inductor core. Non-metallic magnetic materials because of its exceptional quality for wireless electronics technology has a very important help, many scientists are working on a non-metallic magnetic materials research, trying to play its biggest role.
　　We can say that the magnetic material in the electronics, information technology, machinery production, industrial production and other aspects have a closely linked, in which the role can not be ignored.
