Magnets in which magnetic fields are produced by electric current. By manipulating the electric current, the magnetic fields can be changed and manipulated as well, which allows more control than permanent non-electric magnets. Electromagnets are commonly used in electrical devices, such as loudspeakers, hard disks, MRI devices, and electric motors.
