An infinitely long cylinder is kept parallel to an uniform magnetic field B directed along positive z-axis. The direction of induced current as seen from the z-axis will be

Options

A. clockwise of the +ve z-axis
B. anticlockwise of the +ve z-axis
C. zero
D. along the magnetic field.

Answer

C

Explanation

Since the magnetic field is uniform, hence there is no change in the magnetic flux linked with cylindrical wire and hence no current will be induced on the surface of cylindrical wire.
