Conducting square loop of side L and re...

Conducting square loop of side `L` and resistance `R` moves in its plane with a uniform velocity `v` perpendicular to one of its sides. A magnetic induction `B`, constant in time and space, pointing perpendicular and into the plane of the loop exists everywhere.
The current induced in the loop is

A

(a) `BLv//R` clockwise

B

(b) `BLv//R` anticlockwise

C

(c ) `2BLv//R` anticlockwise

D

(d) zero

Text Solution

Verified by Experts

The correct Answer is:
D

Since the rate of change of magnetic flux is zero, hance there will be no net induced emf and haence no current flowing in the loop.
