Vedclass · Answer

(B) The correct answer is $B$. The direction of the induced e.m.f. and the resulting induced current in a closed loop is determined by Lenz's Law.Lenz's Law states that the polarity of the induced e.m.f. is such that it produces a current whose magnetic field opposes the change in magnetic flux that produced it.This is a direct consequence of the law of conservation of energy.
