Question

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 net repulsive force away from the conductor, a net torque acting upward perpendicular to the horizontal plane, a net torque acting downward normal to the horizontal plane, a net attractive force towards the conductor

$ ​ F 2 ​ = − F 4 ​ F 1 ​ = 2 π d μ 0 ​ I 1 ​ I l ​ F 2 ​ = 2 π ( d + l ) μ 0 ​ I 1 ​ I l ​ F 1 ​ > F 3 ​ F net ​ = F 1 ​ − F 3 ​ ​ $ So, wire atrract loop.
