Q152 / 160 · TS EAMCET 2021 (05 Aug Shift 2) · Physics

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

Correct answer
A
zero
B
along the magnetic field
C
clockwise of the $+ v e z$ -axis
D
anti-clockwise of the $+ v e z$ -axis

Solution

Current is induced only when magnetic flux changes w.r.t. time. In the given case neither magnetic field change nor area changes, so flux will be constant, so induced current will be zero.

Hence, the correct answer is option: 'A'.
