Question:

A square loop, carrying a steady current I, is placed in a horizontal plane near a long straight conductor carrying steady current I1 at a distance d from the conductor. The loop will experience:

A net torque acting downward normal to the horizontal plane

A net torque acting upward perpendicular to the horizontal plane

A net repulsive force away from the conductor

A net attractive force towards the conductor

Solution:

F1>F2. Hence net attraction force will be towards conductor.
