What are electromagnets used for ks3?

A simple electromagnet is made by coiling wire around an iron nail. Electromagnets are used in devices such as electric bells, and door locks that can be controlled remotely.

How do headphones use electromagnets?

Headphones consist of two magnets. Inside the headphone there is a cone-shaped diaphragm. It is wound to a coil of wire which acts as an electromagnet i.e. when current flows inside the wire, magnetic field is induced. Thus the wire behaves as a magnet when current enters the wire.
