### Inductor Wikipedia Republished // WIKI 2

An inductor usually consists of a coil of conducting material, typically insulated copper wire, wrapped around a core either of plastic (to create an air-core inductor) or of a ferromagnetic (or ferrimagnetic) material; the latter is called an "iron core" inductor.Since power inductors require high induction levels, high permeability and low saturation points in the core materials are not ideal. Inductor - Definition, Types, Formula, Functions, Working An inductor is a passive component that is used in most power electronic circuits to store energy in the form of magnetic energy when electricity is applied to it. One of the key properties of an inductor is that it impedes or opposes any change in the amount of current flowing through it.
