The classification of the introduction to the magnet magnetic material materials mainly include two categories: the first is the permanent magnetic material (
Also called hard magnetic)
: the characteristics of the magnetic material itself has set.
The second is soft magnetic (
Also called electromagnet)
: need outside power to produce magnetic force, we mean the magnets, generally refers to the permanent magnetic material.
Permanent magnetic material has two categories: the first major categories are: magnet permanent magnetic materials (including rare earth permanent magnet materials
, samarium cobalt (
, nickel and cobalt neodymium (
The second major categories are: ferrite permanent magnet material (
According to the different production process can be divided into: sintered ferrite (
, bonded ferrite (
Rubber and plastic magnetic Rubber all)
, injection ferrite (
, the magnet process on the basis of the magnetic crystal orientation of the three different each divided into isotropic and different sex magnets.
