    The wand's advantage lies in its demagnetizing other metal parts of the tape path, not just the heads. Used carelessly, it can increase the magnetization of the heads; if used too close to tapes, it can erase them. Both of these types of demagnetizer contain electronic circuitry and require a power source (either a battery or a power cord).

    en.wikipedia.org/wiki/Degaussing

    In tape recorders such as reel-to-reel and compact cassette audio tape recorders, remnant magnetic fields will over time gather on metal parts such as guide posts tape heads. These are points that come into contact with the magnetic tape. The remnant fields can cause an increase in audible background noise during playback.

  7. Reel-to-reel audio tape recording - Wikipedia

    en.wikipedia.org/wiki/Reel-to-reel_audio_tape...

    As the tape moves over the recording head, the head's magnetic field varies with the sound thus varying the magnetism on the passing particles of metal oxide on the tape. [ 11 ] In playback mode, the recording head becomes a playback head and senses the magnetism of the metallic particles on the tape as the tape was pulled across the head.
