I don't understand part c, it asked me to suggest a way to make the coil to rotate continuously.
1.clockwise,anti-clockwise isn't the same as opposite torque?
2.why won't the coil stops at B with the solution's set-up?

1. Opposite torques give rise to alternate clockwise and anticlockwise motion.

2. Because the current is being cut off by the non-conducting paint at this orientation, there is no torque acting on the rotating coil. The coil continues to rotate due to inertia.
