:) Thank you sir. If this were yahoo answers I would give you the +10 thing! One thing I love about PhysicsF(even before I had an account), You truley learn the process/thinking. That is evident for me here, thank you!
Thank You Mr./Mrs. Gneill. Okay so at z=o if r=a The wire on the left would have a vector pointed in the direction of the negative z axis, the wire on theright would have a vector equal in magnitude but pointed in the positive z axis and thus the magnetic field would be zero there. Now what you...
Umm, the diagram has the current flowing from the positive x-axis into the - x axis. The problem does not state the magnitudes of the currents but I will make an assumption that they are and make a note of that on mt paper.
Two infinitely long wires are in the negative x direction. The wires are separated by distance 2a. They are parallele to one another. They lie along the x-axis with x = o being in the middle.Both wires are at z = 0.

(b) At what distance d...
