A coil of wire with an electric current flowing through it becomes a magnet. Putting iron inside a current-carrying coil greatly increases the strength of the electromagnet.

Coil is placed in a magnetic field. When current is passed through the the coil placed inside the magnetic field, the electromagnetic force is produced and it rotates the coil. Thus electric current is converted into mechanical energy. The shaft rotates, which rotates the components connected to it.
