Answer:
Yes, it will.
Explanation:
Using Flemings right hand rule, where the forefinger points to the direction of the magnetic field, the middle finger points in the direction of the current and the thumb gives the direction of force or motion acting on the conductor. One can observe from the attached image that the force on both sides of the ring pull the ring out, which increases the angle. Therefore, the net torque acting on the loop is positive and tends to rotate the loop in the direction of increasing angle θ (counterclockwise).
