What are the three broad categories of magnetic materials that can be classified according to their uses?
Anti magnetic material is magnetized strength is weak, the magnetic field in the opposite direction and the direction of the magnetic field, external magnetic field magnetic removed almost completely disappeared.
Roughly divided into three classes: paramagnetic, diamagnetic, ferromagneticParamagnetic material is magnetized strength is very weak, the magnetic field direction and the direction of the original magnetic field, external magnetic field magnetic removed almost completely disappeared.
Ferromagnetic material is of strong magnetic material, the magnetized strength is very strong, and the direction of the magnetic field and magnetic field direction, removed from the magnetic field, the magnetic still remaining part of the magnetic material of this kind of material is usually said. The degree of difficulty of magnetic materials are magnetized to magnetic can be divided into two categories: after magnetization easy to get rid of the magnetic substance called soft magnetic materials, the magnetic not easy to magnetic substance called hard magnetic material.
