COMPOSITE MAGNETIC MATERIAL AND PRODUCT FOR ELIMINATING ELECTROMAGNETIC INTERFERENCE

摘要

A composite magnetic material used for a product that effectively eliminates electromagnetic interference in radio-frequency electronic appliances, particularly mobile communication equipment. The composite magnetic material is a nonconductor comprising soft magnetic powder and an organic binder, and it can be in magnetic resonance in at least two directions with at least two different magnetic fields (Hk) having different magnitudes.
