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
