    If \[i\] is increasing continuously, then find the direction of induced current in the loop.

    A)  Anticlockwise

    B)  Clockwise

    C)  In any direction

    D)  No current will be induced

    Correct Answer: A

    Solution :

    At the location of loop, magnetic field is perpendicular to plane of paper and going into it, which is increasing with time as current is increasing. Therefore, emf will be induced in the loop in such a way so that induced current will produce magnetic field as such it opposes the original magnetic field in accordance with Lenzs law. Thus, current is induced in the loop in anticlockwise direction.
