Once the field is built, current can flow normally through the wire. When the switch gets opened, the magnetic field around the coil keeps current flowing in the coil until the field collapses. This current keeps the bulb lit for a period of time even though the switch is open. In other words, an inductor can store energy in its magnetic field ...

Energy storage is possible BUT inductors tend to be physically large at high iunductance compared with capacitors. eg 1A in 1H gives E=1/2 x L x i^2 = 1/2 x 1 x 1^2 = 0.5J. A 1F supercap at 1V contains the same energy. – Russell McMahon ♦. Aug 11, 2017 at 14:42. The sole Digikey inductor rate at >=1A and >= 1H costs $73.

If the current flowing through the inductor is constant as in a DC circuit, then there is no change in the stored energy as P = Li(di/dt) = 0.
