Lenz's law of electromagnetic induction states that
A. a force is exerted on a current-carrying conductor in a magnetic field B. electromotive force id induced in a circuit whenever there is a change in the magnetic flux linked with the circuit C. the magnitude of the induced electromotive force in a circuit is proportional to the rate of change of flux linking the circuit D. the induced current in a coil is in such a direction that it sets up a magnetic field which opposes the change producing it
