In the figure, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 4.67 cm. Each wire carries 11.2 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 0.00085 Units N/m a a 2
