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 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

Text Solution

Verified by Experts

The correct Answer is:
D

`F = I xx l xx B`
B is near the wire . So a net attractive force towards the conductor is there .
