Background

Demagnetizers are also called demagnetizers. One device for eliminating residual magnetism on a magnetized object is known as a demagnetizer. The degaussing mode is divided into permanent magnet, direct current and alternating current. The demagnetizer of broadcasting system is mainly used to eliminate the residual magnetism on the recorded program signal and recording mechanism, relative accessories and tools on the recording tape. Demagnetizers typically employ electromagnets with no closed core, energized with 50 hz alternating current. When demagnetizing, the demagnetized object is first made to approach the demagnetizer to make the magnetism reach saturation, then gradually leave, so the hysteresis loop is gradually reduced until the remanence is eliminated. The damping oscillation current can also be led into the coil of the electromagnet to be used as a demagnetizer. When using such a degausser, the degaussed object does not have to be moved away gradually.
