I understand that in an ideal world, an inductor will not hold a charge (when not connected to a circuit). Ideally, there would need to be a current through the inductor to generate a B-field to store energy. I once read, that (since this is not an ideal world), an inductor actually CAN and WILL hold a charge, rather than fully discharging when disconnected from a circuit. I'm looking for a valid argument either way. Thanks!
