    Two different wire loops are concentric and lie in the same plane. The current in the outer loop (I) is clockwise and increases with time. The induced current in the inner loop    

    A) is clockwise         

    B)        is zero                 

    C) is counter clockwise    

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

    Correct Answer: C

    Solution :

    [c] As I increases, \[(\phi )\] increases \[\therefore \]     \[{{I}_{i}}\] is such that it opposes the increases in \[\phi \]Hence, \[\phi \] decreases (By Right Hand Rule). The induced current will be counter-clockwise.
