Permanent ferrite magnet is made of SrO or BaO and Fe2O3Â by ceramic processing technology.
Anisotropic sintered ferrite magnets have higher magnetic properties compare with isotropic ferrite magnet.
However, this type of magnets can only be magnetized along the preferred direction;the sintered Ferrite has
an excellent resistance to demagnetization.Â
Â
The Polar Anisotropic Ferrite Ring Magnets are the magnets with multipoles in ring shape. They have
become the key component of stepping motors which are widely used in computer peripheral and
consumer electronics, such as washing machine,different types of pumps, Â printer and digital -camera,etc.
