Figure P20.57 shows several different current loops in a magnetic field.
In case 1, the black line is drawn along the axis of the loop and the current is clockwise when viewed from the upper left.
In case 2, the black line is drawn along the axis of the loop and the current is clockwise when viewed from the upper right.
In case 3, the black line is in the plane of the loop, passing through the centers of two arms of the loop, and the current is clockwise when viewed from above. What is the direction of the torque on each current loop? Express your answer as either clockwise or counterclockwise as viewed along an axis perpendicular to the plane of the drawing.
