What is an inductor coil？

An inductor is an electrical component designed to store energy in the form of a magnetic field as current flows through it. It consists of a coil, usually wound around a core material such as iron, that helps increase the magnetic field of the inductor. As current flows through the coil, it creates a magnetic field around the inductor.

If the current flowing through the inductor is suddenly interrupted or changed, the magnetic field collapses, causing a voltage to be induced in the inductor windings. This induced voltage can then be used to perform various functions, such as filtering electrical signals or storing energy.

Inductor coils are used in a wide variety of electronic circuits, including power supplies, radios, and televisions.
