HI,
I am thinking about storing energy in an inductor coil for indifinate time. My idea is to charge inductor coil through a battery connected in series with the coil. Now when i remove the battery from the circuit, the inductor cannot discharge the magnetic field as it is an open circuit. Inductor should discharge this energy only when the circuit is closed. So the magnetic field energy should remain for any period of time. please explain if i am wrong?
