A conducting bar of length L is free to slide on two parallel conducting rails as shown in the figure
Two resistors $\displaystyle R_1$ and $\displaystyle R_2$ are connected across the ends of the rails. There is a uniform magnetic field $\displaystyle \vec{B}$ pointing into the page. An external agent pulls the bar to the left at a constant speed $\displaystyle v$.
The correct statement about the directions of induced currents $\displaystyle \mathrm{I}_1$ and $\displaystyle \mathrm{I}_2$ flowing through $\displaystyle R_1$ and $\displaystyle R_2$ respectively is :
Official answer
(2)
$\displaystyle \mathrm{I}_1$ is in clockwise direction and $\displaystyle \mathrm{I}_2$ is in anticlockwise direction
