Answer:

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.

Electromagnets are basically coils of wire which behave like bar magnets with a distinct north and south pole when an electrical current passes through the coil.

Electromagnets are very widely used in electric and electromechanical devices, including:

Motors and generators

Transformers

Pickups

Relays

Electric bells and buzzers

Loudspeakers and headphones

Actuators such as valves

Magnetic recording and data storage equipment: tape recorders, VCRs, hard disks
