    Two different loops are concentric and lie in the same plane. The current in the outer loop is clockwise and increasing with time. The induced current in the inner loop, is:

    A) clockwise                      

    B) zero

    C) counter-clockwise

    D) in a direction that depends on the ratio of the loop radii

    Correct Answer: C

    Solution :

    (c) counter-clockwise According to Lenz's law, induced current will be in such a direction so that it opposes the change due to which it is produced. So induced current in the inner loop will be in counter-clockwise direction.
