Two long, parallelwires separated by a distance2d carry
Chapter , Problem 54(choose chapter or problem)
Two long, parallelwires separated by a distance2d carry equal currents in thesame direction. An end view ofthe two wires is shown in FigureP19.54, where the currents areout of the page. (a) What is thedirection of the magnetic fieldat P on the x-axis set up by thetwo wires? (b) Find an expression for the magnitudeof the field at P. (c) From your result to part (b), determinethe field at a point midway between the two wires.Does your result meet with your expectation? Explain.
