    The graph shows the variation in magnetic flux \[\varphi (t)\] with time through a coil. Which of the statements given below is not correct                                           [AMU (Engg.) 2001]                                                                                                                                                       

    A)            There is a change in the direction as well as magnitude of the induced emf between B and D

    B)            The magnitude of the induced emf is maximum between B and C

    C)            There is a change in the direction as well as magnitude of induced emf between A and C

    D)            The induced emf is zero at B

    Correct Answer: D

    Solution :

               At B, flux is maximum, so from \[|e|=\frac{d\varphi }{dt}\] at B \[|e|=0\]
