Four long straight wires are perpendicular to the page, andtheircross sections form a square of edge length a=13.5cm. Eachwirecarries 7.50 A, and the currents are out of the page in wires1 and4 and into the page in wires 2 and 3. In unit vectornotation, whatis the net magnetic force per meter of wire lengthon wire 4?
This problem has been attempted once, but i could no followit.Could someone please explain it? The answer is(-125microN/m)i +(41.7microN/m)j. I'll rate lifesavertonight if you can help.
