Question

A square loop, carrying a steady current $I$, is placed in a horizontal plane near a long straight conductor carrying steady current $I_1$ at a distance $d$ 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

Answer 1

The correct option is D A net attractive force towards the conductor

$F_1>F_2$. Hence net attraction force will be towards conductor.
