    The long, straight wire as shown in the figure, carries a current i to the right that increases with time. What is the direction of the induced current in the circular wire loop, which lies in a plane perpendicular to the wire?

    A)  Clockwise as viewed from the right.

    B)  Counterclockwise as viewed from the right.

    C)  There is no induced current.

    D)  The induced current is alternating.

    Correct Answer: C

    Solution :

    The magnetic field lines of the current carrying wire will be concentric circles in the plane of the circular wire loop, so the magnetic field and the area vector are perpendicular to each other. This means that the magnetic flux through the loop always remains zero, so there is no possibility of induced current. Hence, the correction option is [c].
