Faraday's law of induction

A statement relating an induced electromotive force (emf) to the change in magnetic flux that produces it. For any flux change that takes place in a circuit, Faraday's law states that the magnitude of the emf ξ induced in the circuit is proportional to the rate of change of flux as in the expression below. The time rate of change of flux in this expression may refer to any kind of flux change that takes place. If the change is motion of a conductor through a field, dΦ/dt refers to the rate of cutting flux. If the change is an increase or decrease in flux linking a coil, dΦ/dt refers to the rate of such change. It may refer to a motion or to a change that involves no motion.
