Question

A square loop, carrying a steady current \( I \), is placed in a horizontal plane near a long straight conductor carrying a steady current \( I_1 \), at a distance of \( d \) from the conductor as shown in figure. The loop will experience

• A. a net repulsive force away from the conductor
• B. a net torque acting upward perpendicular to the horizontal plane
• C. a net torque acting downward normal to the horizontal plane
• D. a net attractive force towards the conductor

Hint:

For two parallel currents in the same direction, the magnetic force between them is attractive.

Answer 1

The Correct Option is D

The loop carrying a steady current will experience a force due to the magnetic field created by the other current. Since the currents are in the same direction, the loop will experience an attractive force towards the conductor.

Step 2: Conclusion.
The correct answer is (d) a net attractive force towards the conductor.
