Two long, parallel transmission lines, 40.0cm apart, carry 25.0-A and 73.0-A currents. A). Find all locations where the net magnetic field of the two wires is zero if these currents are in the same direction. Assume that the positive x axis is directed from the 73.0-A wire to the 25.0-A wire perpendicular to the wires, with the origin on the 73.0-A wire. B). Find all locations where the net magnetic field of the two wires is zero if these currents are in the opposite direction. Assume that the positive x axis is directed from the 73.0-A wire to the 25.0-A wire perpendicular to the wires, with the origin on the 73.0-A wire.
