When will a loop rotate in a clockwise direction?

A loop will rotate in a clockwise direction when a loop of wire carrying a current has the current running in opposite directions on either side of the loop, e.g. on the left, the current runs back to front, but on the right, it runs front to back. Then the loop is placed in a magnetic field where it experiences a force on the left, that acts up, and force on the right that acts down. Therefore a moment is created on the left and a moment is created on the right, so it rotates in a clockwise direction. But it will stop rotating when it reaches 90 degrees.
