Question:

Consider an infinitely long conductor XY carrying current (x) A. A rectangular loop carrying current 2 A is placed parallel to it in the same plane. The two conductors are found to exert a force of 1.8 × 10–5 N/M. Find the value of x.

Options:

0.6 A

3 × 102 A

3 A

3 × 10-2 A

Correct Answer:

0.6 A

Explanation:

As distance between wire XY and AB is required to calculate magnetic force between parallel currents. It is not given so data is insufficient to calculate the force.
