In the figure, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 7.54 cm. Each wire carries 11.3 A, and all the currents are out of the page. What is the magnitude of the net magnetic force per unit length on wire 1? Number i a 3 -X Units
