(a) A loop of current in the yz plane has a current in the counter-clockwise direction. What is the direction of the magnetic moment?
(b) A loop of current is placed in the xy plane in a uniform magnetic field in the positive x direction. If the current in the loop is in the clockwise direction, what is the direction of the torque on the loop?
(c) A filamentary current along the x-axis has a current in the a-x direction. A square loop of current in the xy plane centered at (0, 10, 0) has a current in the counter-clockwise direction. What is the direction of the net force on the loop?
