A coil typically consists of multiple turns of magnet wire around a winding form. The magnet wire can be made of copper with an insulating film. Winding multiple turns of wire in the shape of a coil enhances the magnetic field created when electric current flows through the wire. The coil is useful for storing energy, smoothing or filtering current, or transferring energy to other coils.
Coils are often used in high-frequency specialty applications, such as antennas and electronic filters. They are a fundamental component of transformers, inductors, and chokes. While a transformer has a coil (or multiple coils), a coil is not necessarily a transformer.
