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.
