1) A square loop, carrying a steady current I. is placed in a horizontal plane near a long straight conductor carrying a steady current I1 at a distance d from the conductor as shown in the 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: Option DExplanation:F1 > F2 as $F \propto\frac{1}{d}$, and F3 and F4 are equal and opposite. Hence, the net attraction force will be towards the conductor.
