All electric motors use electromagnets . Audiotape and videotape players have electromagnets called heads that record and read information on tapes coverd with tiny magnetic particles. Magnets in speakers transform the signal into a sound by making the speakers vibrate. An electromagnet called a deflection yoke in TV picture tubes helps form images on a screen. Magnetic tapes and disks.
Powerful cranes use an electromagnetics to move scrap iron and steel, seperate metals for recycling.
Generators in powerplants rely on magnets like the ones found in electric motors to produce electricity. Scientists and engenieers have developed trains that use electromagnetics to float it above the track. They also use the repeling force of a magnet to levitate the train. It eliminates friction so it has an advantage of higher speeds over ordinary trains. In Science and medicine bending magnets are very powerful magnets which help control beams of atomic particles which is boosted into high speed devices called particle accelerators.
