The wire is then placed in an upward pointing external magnetic field as shown in the side view to the right. The wire loop has a central axis about which it is free to Loop may rotate about a central axis rotate. Starting at rest from the position shown, the wire will. (A) start to rotate clockwise. (B) start to rotate counter-clockwise. Current out of page on bottom (C) remain at rest, because the torques present sum to zero. (D) remain at rest, because the magnetic field will not cause any torques in the orientation shown.
