The working principle of an inductor is rooted in electromagnetic induction. When an electric current flows through a coil of wire, it generates a magnetic field around the coil. This magnetic field stores energy. If the current changes, the magnetic field also changes, inducing a voltage (electromotive force) in the coil.
