Question

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 $\overrightarrow{B}$ 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 :

• A. Both $I_1$ and $I_2$ are in anticlockwise direction
• B. Both $I_1$ and $I_2$ are in clockwise direction
• C. $I_1$ is in clockwise direction and $I_2$ is in anticlockwise direction
• D. $I_1$ is in anticlockwise direction and $I_2$ is in clockwise direction

Answer 1

Answer: (C)

Correct answer is (c) $I_1$ is in clockwise direction and $I_2$ is in anticlockwise direction
