... Lenz's law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in flux or to exert a mechanical force opposing the motion. The total amount of electromagnetic energy cannot change! Eddy currents (also called Foucault cur ...
