Energy stored in an inductor. The energy stored in an inductor is due to the magnetic field created by the current flowing through it. As the current through the inductor changes, the magnetic field also changes, and energy is either stored or released. The energy stored in an inductor can be expressed as: W = (1/2) * L * I^2
