In the figure below, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a. Each wire carries current i, and all the currents are out of the page. What is the magnitude of the net magnetic force per unit length on wire 1? (Use any variable or symbol stated above along with the following as necessary: Mo.) E = a a a a -O 3
In the figure below, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 12.0 cm. Each wire carries 6.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3. What is the magnitude and direction of the net magnetic force per meter of wire length on wire 4? magnitude 6.63E-5 X N/m direction 45 X (counterclockwise from the positive x axis) a a a
