What are they used for?
Electromagnets are widely used in technology and are the essential components of relays and circuit breakers. Electromagnets are also used in electromagnetic clutches and brakes. In some streetcars, electromagnetic brakes grip directly onto the rails. Very large electromagnets having cores several meters in diameter are used in cyclotrons, and high-power electromagnets are used to lift iron parts or scrap.
