Question

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

Two resistors R₁ and R₂ are connected across the ends of the rails. There is a uniform magnetic field `vec"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 I₁ and I₂ flowing through R₁ and R₂ respectively is:

विकल्प

• I₁ is in clockwise direction and I₂ is in anticlockwise direction.

• Both I₁ and I₂ are in clockwise direction.

• I₁ is in anticlockwise direction and I₂ is in clockwise direction.

• Both I₁ and I₂ are in anticlockwise direction.

Answer 1

I₁ is in the clockwise direction and I₂ is in the anticlockwise direction.

Explanation:

When the bar moves to the left, the area of loop 1 decreases, increasing magnetic flux current flow in the clockwise direction, and the area of loop 2 increases, increasing current flow in the anticlockwise direction.
