A conducting bar of length $L$ is free to slide on two parallel conducting rails as shown in the figure

Two resistors ${R}_{1}$ and ${R}_{2}$ are connected across the ends of the rails. There is a uniform magnetic field $\overset{\to}{B}$ pointing into the page. An external agent pulls the bar to the left at a constant speed $v$.

The correct statement about the directions of induced currents ${I}_{1}$ and ${I}_{2}$ flowing through ${R}_{1}$ and ${R}_{2}$ respectively is :
