Energy stored in the magnetic field
WebIn case of an inductor, this energy is stored in the magnetic field of the inductor with steady current I I. As the current decreases from I I to 0, this energy is released again. … WebEnergy in an Inductor. When 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.
