How do inductors store energy?

The energy in a capacitor can be thought as being stored in the electric field. The energy is stored in the magnetic field for an inductor which needs to have charges moving, an electric current. So if the current is reduced or eventually made zero the magnetic field would be reduced and so the energy stored in the inductor decreases. –
