According to the right-hand rule for the cross product, if the thumb points towards the viewer (11eab079_97a6_bde1_a51f_efeb874a2818_TB6585_11), the curl of the fingers will indicate a counterclockwise direction. Therefore, the path integral must be counterclockwise around the circumference of the paper.
