Choose the wrong statement :

A

Whenever the amount of magnetic flux linked wita circuit, an e.m.f. induced in the circuit.

B

The induced e.m.f. lasts so long as the change in magnetic flux continues.

C

Larger the amount of magnetic flux linked with a circuit, greater is the e.m.f. induced in it.

D

The direction of induced e.m.f. is given by Lenz's Law.
