Question

Two different wire loops are concentric and lie in the same plane. The current in the outer loop (I) is clockwise and increases with time. The induced current in the inner loop.

Options

• is clockwise.

• is zero.

• is counter clockwise.

• has a direction that depend on the ratio of the loop radii.

Answer 1

is counter clockwise.

Explanation:

As I increase in the outer loop, `phi` increases Current in the inner loop is such that it opposes the increase in `phi`. Hence `phi` decreases (By Right Hand Rule). The induced current will be counterclockwise.
