Assertion (A) : It is difficult to move a magnet into a coil of large number of turns when the circuit of the coil is closed.
Reason (R) : The direction of induced current in a coil with its circuit closed, due to motion of a magnet, is such that it opposes the cause.
Official answer
(A)
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
