Metal oxide Magnetic Materials EE Series

A material that can react in some way to a magnetic field is called a magnetic material.According to the strength of the magnetism of the material in the external magnetic field, it can be divided into antimagnetic substance, paramagnetic substance, ferromagnetic substance, antiferromagnetic substance and ferrous magnetic substance.Most materials are diamagnetic or paramagnetic, and they have a weak response to the external magnetic field.Ferromagnetic materials and ferromagnetic materials are strong magnetic materials.For magnetic materials, the magnetization curve and hysteresis loop are characteristic curves reflecting their basic magnetic energy.Ferromagnetic materials are generally Fe, Co, Ni elements and their alloys, rare earth elements and their alloys, and some compounds of Mn.Magnetic materials are generally classified into soft magnetic materials and hard magnetic materials according to their ease of magnetization.
