yeah and the maximum occurs when z=a

I notice that directly above each wire you have the magnetic field completely horizontal. is it ok to ignore the slight downward or upward effect that the other wire will have on the original wire

no they don't cancel along the z axis (except at z=0). the z component of the magnetic field cancels along that axis but the y component of both actually add. It's a balancing act between the angle that they are at (and hence the y component of the magnetic field) and the distance from the...
