Hi all, I have a question which relates to induction and one potentially useful property of superconductors which seems to suggest one intriguing posibility. I wont say what just yet since my science is potentially a bit rusty, so don't want to sound like a fool. As I understand it, after an electric current stops flowing through an inductor, the magnetic energy around the inductor's coil is absorbed by the coil, creating a spike in electrical energy. But what if the inductor's coil is made of a superconducting material, which if I understand superconductors correctly, is suposed to repel magnetic fields. When the applied current stops flowing, the residual magnetic field around the coil can not be absorbed as electrical energy so my expectation is that there would be a repulsive force between the residual magnetic field and the inductive coil, which may produce a kinetic force. Does anyone know whether this is true or not?
