Hello All, Was thinking about some of the basic concepts of magnetic induction, in the case of a stationary solenoid coil with a moving magnet crossing the face of the coil. We know that when the magnet approaches the face of the coil and the field increases, that a votlage potential (emf) is induced in the windings, which generates a current, i, in the windings. Also, as the magnet proceeds past the face of the coil, the magnetic field decreases and the opposite voltage potential is induced in the coil and a current is driven in the opposite direction. Now assuming that I'm on par so far, I have made the assumption in the above example that the coil was either shorted to itself or across a load of some sort so that a current can actually flow when the emf from the magnet is induced into the windings. But what would happen if the coil was open-circuited while the magnet was approaching the coil, but then shorted to itself right as the magnet passed over the face of the coil? Would a current still be generated at that point in time (assuming that the magnetic field has not yet started decreasing). If a current is generated at this point, was the energy stored capacitively in the windings while the magnet was approaching and the coil was open-circuited? Or would nothing at all happen? Thanks, Jason O EDIT: Argh.. Typos!
