Lenz's law of electromagnet states that

A The induced charge is constant for a fixed change of force
B A force is exerted on a current-carrying conductor in a magnetic field
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 The induced current in a conductor is in such a direction as to oppose the change producing it
E E.m.f. is induced in a circuit whenever there is a change in the magnetic flux linked with the circuit
