**Charlotte**, Friday, February 1, 2013 at 3:36pmIf the currents are flowing in the same direction, they repel one another and you take the difference of I for wires in parallel with each other. If they flow in the same direction you take the sum of I. Do that for both sides of parallel lines and add your equations then set the equation equal to the net magnetic field in the center.
