Inductors store energy as a magnetic field, which is returned to the circuit when the field collapses. This happens every half cycle, and as there is no resistance (in theory), there are no losses, and all of the energy is returned to the circuit. Figure 1 shows the applied voltage as the red sine wave and the back EMF as the green sine wave.
