A conducting loop is being pulled with speed v from region I of magnetic field to region II. If resistance of the loop is R, current induced in the loop at the instant shown is:

A) \[\frac{{{B}_{0}}\ell v}{R},\] clockwise

B) \[\frac{{{B}_{0}}\ell v}{R},\]anticlockwise

C)  \[\frac{3{{B}_{0}}\ell v}{R},\]clockwise

D) \[\frac{3{{B}_{0}}\ell v}{R},\] anticlockwise

Correct Answer: C

Solution :

\[i=\frac{3{{B}_{0}}v\ell }{R}\]
