Energy in an InductorWhen a electric current is flowing in an inductor, there is energy stored in the magnetic field. Considering a pure inductor L, the instantaneous power which must be supplied to initiate the current in the inductor is so the energy input to build to a final current i is given by the integral Using the example of a solenoid, an expression for the energy density can be obtained.
