Permanent ferrite magnetic tile ( hereinafter referred to as magnetic tile ) is widely used in the stator of the motor, which is usually within the arc face , closely related to the magnetic flux density and motor performance it provides. Therefore, the problem of the magnetic flux density within the arc tile provide , either magnetic or magnetic tile tile maker users ( motor manufacturers ) are of particular concern . Many businesses in order to improve the magnetic flux density watt arc done a lot of work .
Ferrite head mainly for video recorders, fast copying machines, floppy disk drive and hard disk drive high- density magnetic recording device. Making such a head , in addition to forming the gap with advanced technology , super- fine grinding and other processing and surface treatment technology , but also requires the heads of the material itself has a high magnetic permeability ( the band work ) , high magnetic flux density , high density and very good fracture toughness.
