Processing method of electromagnetic shielding magnetic material

The invention discloses a processing method of an electromagnetic shielding magnetic material. A soft magnetic alloy magnetic material strip is wound into a soft magnetic alloy magnetic material ring,and the ring is installed a thermal processing furnace; protection gas is injected into the thermal processing furnace and the furnace is heated after the furnace is vacuumized, the furnace temperature is kept, a longitudinal magnetic field and a transverse magnetic field are exerted on the magnetic material through an alternating pulse current A and an alternating pulse current B, and cooling isconducted; after the thermally-processed soft magnetic alloy magnetic material ring is attached to double-sided adhesive tape with a PET base material to form a tape-covered magnetic material strip belt, ultrasonic vibrating, roller pressing and smashing are conducted on the tape-covered magnetic material strip belt to form soft magnetic alloy roller pressing strip belts, and the soft magnetic alloy roller pressing strip
