A conducting square loop of side l and resistance R moves in its plane with a uniform velocity v perpendicular ot one of its sides. A uniform and constant magnetic field B exists along the perpendicualr ot the plane of the loop as shown in . The current induced in the loop is
(##HCV_VOL2_C38_E01_025_Q01##)

A

BLv/R clockwise

B

BLv/R anticlockwise

C

2 BL/R anticlockwise

D

zero

Text Solution

Verified by Experts

The correct Answer is:
4
Since the magnetic induction is uniform the flux, phi, through the square loop at any time t, is
`phi =BxxA=BxxL^(2)` = constant
Hence,` e=(-dphi))/(dt)` = zero
