Anisotropic Ferrite Magnet Ring Type

Brand :

MAGNA

Caution

Product Description

Ferrite Magnet Circular Type.
[Features]
· It has a high coercive force, so there is no demagnetization.
· As a sintered magnet (ceramic magnet), it offers excellent corrosion resistance and is suitable for flat shapes, but on the other hand, it has the drawback of being prone to cracking.
· In addition to conventional audio speakers and headphones, demand for automotive motor and generator use is further increasing due to weight reduction through technological innovation (to half or one-third of the conventional weight).
[Applications]
· Various devices for electronic equipment, and for automotive motors and generators. A wide range of products including stationery, household goods, and health devices.
