Lenz’s law of electromagnetic induction states that
-
A.
electromotive force 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 induced e.m.f. in a circuit is proportional to the rate of change of number of lines of force linking the circuit -
D.
a force is exerted on a current carrying conductor in a magnetic field -
E.
the induced e.m.f. is proportional to the current producing the magnetic flux.
