A square loop, carrying a teady current , is placed in a horizontal plane near a long straight conductor carrying a steady current 1 at a distance d from the conductor as shown in figure. The loop will experience


- Aa net attractive force towards the conductor
- Ba net repulsive force away from the conductor
- Ca net torque acting upward perpendicular to the horizontal plane
- Da net torque acting downward normal to horizontal plane
View written solutionFree
Correct answer: A

as , and and are equal and opposite. Hence, the net attraction force will be towards the conductor.
