38. The two wires shown in Figure P19.38 carry currents of 5.00 A in opposite directions and are separated by 10.0 cm. Find the direction and magnitude of the net magnetic field (a) at a point midway between the wires, (b) at point P1 (10.0 cm to the right of the wire on the right), and (c) at point P2 (20.0 cm to the left of the wire on the left).
