Question

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 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
