two long straight wires are perpendicular to the page and separated by distance d1 = 8.8 cm. Wire 2 carries a current of 3.0 A into the page. What are the magnitude and direction of the current in wire 1 if the net magnetic field due to the two currents is zero at point P located a distance d2 = 12 cm from wire 2?
