    Near a circular loop of conducting wire as shown in the figure an electron moves along a straight line. The direction of the induced current if any in the loop is

    A)  variable                              

    B)  clockwise

    C)  anticlockwise    

    D)         zero

    Correct Answer: A

    Solution :

    Since, electron is moving from left to right, the flux linked with loop will first increase and then decrease as the electron passes by. Therefore, induced current I in the loop will be first clockwise and then will move in anticlockwise direction as the electron passes by.
