A current carrying square loop is placed near a straight infinitely long current carrying wire as shown in figure. The torque acting on the loop is

Recall the formula of torque due to current carrying loop is,
, here are a number of turns, current in the coil, area of the coil and magnetic field here is the angle between area vector and direction of the magnetic field which is (by using right hand thum rule) so torque will be zero.
