Energy stored in an inductor

Energy stored in an inductor is the electrical energy accumulated in the magnetic field created by the flow of current through the inductor. When current passes through the inductor, it generates a magnetic field around it, and this energy can be retrieved when the current changes.

Energy in Inductors: Stored Energy and Operating Characteristics

An alternating current (AC) flowing through the inductor results in the constant storing and delivering of energy. If we have an ideal inductor that has no resistance or capacitance, the energy stores forever without any loss. Actual inductors, though, lose energy and have increased temperatures because of copper loss and core loss.
