WebIn the home, by far the most common use of electromagnets is in electric motors. Think of all of those bits of electrical equipment with some kind of electric motor: vacuum cleaners, refrigerators, washing machines, tumble driers, food blenders, fan ovens, microwaves, dish-washers, hair driers. WebColor CRT displays, the technology underlying many television and computer monitors before the early 2010s, use degaussing. Many CRT displays use a metal plate near the front of the tube to ensure that each electron beam hits the corresponding phosphors of the correct color. If this plate becomes magnetized (e.g. if someone sweeps a magnet on …
