There are many different types of coils used in electric and electronic equipment. In a coil of multiple turns of wire the magnetic field of the turns adds in the center of the coil, creating a strong field. This drawing shows a cross section through the center of the coil.
The IUD or 'coil ' is a small plastic (or plastic and copper) device, not much longer than a match, which is placed inside your womb, where it prevents you from getting pregnant.
Coil, in an electric circuit, one or more turns, usually roughly circular or cylindrical, of current-carrying wire designed to produce a magnetic field or to provide electrical resistance or inductance; in the latter case, a coil is also called a choke coil (see also inductance).

A wire coil is an electrical conductor with one or more turns designed to produce a magnetic field. This is commonly used to increase the strength of a magnetic field. The more turns of wire on the coil, the stronger the magnetic field will be.
Transformers contain two coils: a primary coil and a secondary coil. When alternating current flows through the primary coil, it generates a magnetic field that induces a voltage in the secondary coil.
