Ok, here is a goofy question. Say you have an inductor that is connected in a simple DC circuit and has been there for a "long time". Now if you had a switch that you could move at any speed that you wanted to and could be any distance from the terminal that you wanted it to be what would happen when you disconnected it? Since an inductor resists any change in current would it be able to create any voltage you wanted it to by opening that switch as far as you wanted to. I believe theoretically the answer is yes. You could use the resistance in the air and the distance for the resistive part of the time constant and that would tell you the amount of time that the voltage would exist. Does this mean that when an inductor is removed from a circuit it could never store energy like a capacitor could?
