Lenz's law of electromagnetic induction states that
A. e.m.f. is induced in a circuit whenever there is a change in the magnetic flux linked with the circuit. B. the induced current in a conductor is in such a direction as to oppose the change producing it C. the magnitude of the induced e.m.f. in a circuit is proportional to the rate of change of the number of lines of force linking the circuit D. a force is exerted on a current-carrying conductor in a magnetic Held E. the induced charge is constant for a fixed change of flux.
