As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire ...
Slip rings maintain constant contact with the same sides of the coil As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one direction.
Previous studies have shown that electric fields and/or temperature can rotate ... and phase-field simulation worked together to investigate light-induced physical phenomena in relaxor ferroelectrics.
