Electromagnetic coil. The magnetic field lines (green) of a current-carrying loop of wire pass through the center of the loop, concentrating the field there. An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil ( spiral or helix ).
The electromagnet is a type of temporary magnet in which its magnetic field is produced by electric current and to concentrate the magnetic field, the wire of an electromagnet is wound into a coil.

Sebadoh - Magnet's Coil (Letra y canción para escuchar) - I've gotta find a way to loosen up / I'm wound tighter than a magnet's coil / The longer I try to keep my mouth shut / The sooner little brain is gonna boil /.
Both motors and generators can be explained in terms of a coil that rotates in a magnetic field. In a generator the coil is attached to an external circuit that is then turned. This results in a changing flux, which induces an electromagnetic field.
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 in the center of the coil.
Try this simulation to see how moving a magnet creates a current in a circuit. A light bulb lights up to show when current is flowing, and a voltmeter shows the voltage drop across the light bulb. Try moving the magnet through a four-turn coil and through a two-turn coil. For the same magnet speed, which coil produces a higher voltage?
