    The magnet in figure rotates as shown on a pivot through its centre. At the instant shown, what are the directions of the induced current?

    A) A to B and C to D

    B)        B to A and C to D

    C)        A to B and D to C

    D)        B to A and D to C

    Correct Answer: A

    Solution :

    In the rotation of magnet, N pole moves closer to coil CD and S pole moves closer to coil AB. As per Lenzs law, N pole should develop at the end corresponding to C. Induced current flows from C to D. Again S pole should develop at the end corresponding to B. Therefore, induced current in the coil flows from A to B.
