1. The problem statement, all variables and given/known data Two infinitely long parallel straight wires carry currents in the +- z direction as shwn in the figure below. Each wire is located on the x-axis a distance of a from the origin. a) Determine B as a function of y along the line x=0 b) Sketch a graph of B vs. y along the line x=0, including all values of y. 2. Relevant equations B=u0I/2PiR 3. The attempt at a solution for part a i get u0I/PiR for part b as y increases, B decreases because they're inversely related?
