1. The problem statement, all variables and given/known data I am trying to interpret a diagram of a current distribution, with a view to finding the vector potential. I 'm afraid I don't know how to put images here, so I will try to describe it. In the diagram the x-y plane faces the viewer. In the x direction the diagram shows two arrows facing towards each other. In the y direction the diagram shows two arrows facing exactly away from each other. Next to each arrow there is a lower case i. 3. The attempt at a solution I think it means that the magnitudes of the currents are equal but in different directions. They converge on x and diverge on y, but I'm not sure if this is right, or possible? It seems unlikely to me. If this is correct and I'm not missing anything my solution to finding the vector potential would be simply to make a sum of its x,y,z components. It looks like they would cancel to me though. If anyone could tell me if i'm on the right track or nudge me in the right direction I would be very grateful!
