FERRITE MAGNETS
High Coercive Force
 Used in wide range of applications including speakers, communication equipments,motors, relays, sensors,etc.
Magnets Stability
Magnetized materials tends to be demagnetized due to various external influences during operation. Therefore, it is necessary to perform various stabilizing processes when general magnets are used. However, Ferrite Magnet has high magnetic stability, and its performance is hardly lowered by external disordered magnetic field and machinery shocks, thanks to its great coercive force.

 Temperature Change
 Following tables present temperature change in demagnetization curves of various Ferrite Magnets. Ferrite Magnet has large temperature coefficient of remanence (apparent remanent magnetic flux density) and tends to receive irreversible demagnetization. Therefore, you must be careful of deciding operating point of magnets.
