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?
