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

A

(a) zero

B

(b) anticlockwise of the positive z-axis

C

( c) clockwise ogf the positive z-axiss

D

(d) along with magnetic field

Text Solution

Verified by Experts

The correct Answer is:
A
For a current to induce in the cylindrical conducting rod, the cylindrical rod should cut magnetic lines of force which will happen only when the cylindrical conducting rod is moving. Since conducting rod is at rest, no current will be electric field rod and a current will get induced. But since the magnet field is constant, no current will be induced.
