Answer 1

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 center of the coil.

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

Motors and generators.

Transformers.

Relays.

Electric bells and buzzers.

Loudspeakers and headphones.

Actuators such as valves.

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

MRI machines.
