    The variation of induced emf (e) with time (t) in a coil, if a short bar magnet in moved along its axis with a constant velocity is best represented as follows:

    A)                               

    B)

    C)

    D)  

    Correct Answer: B

    Solution :

    As the magnet moves towards the coil, the magnetic flux increases (non - linearly). Also there is a change of polarity of induced emf when the magnet passes on to the other side of the coil. Hence, the correction option is (b).
