How do you do this problem. If you use superposition you get zero which the problem states is incorrect. How else might you go about the problem?

I would guess (I dont have my book to check) that wires A and C will cancel each other out, leading to the system behaving as if there is only B and D.

Hope that helps, I havent done this sort of problem sense freshman year

That seems right to me. Thanks just wasn't seing that for some reason.

I would think that one would need relitive sizes of the wires to have enough information to solve... Wouldn't the size (and technically the compisition) of wires A, B and C effect the EM output and bias the results accordingly?

we have wires that carry a current, nomatter the thickness, they'll emit a similar b-field from the radius of the wire's edge. any yaws, the currents and firld can be lookd as 2 currents, the AC will act as on, and the BD can act as one. IIRC

You are making the problem too complex. It dosn't tell you to consider any of those things.

The navy sent me to school for this shit. If you can wait a few hours I can probably look through it for you, but I dont really wanna spend my lunch break doing work.

I've already solved it. Then passed my answer by a physics major who is TAing the class. I'm confidant that it is right.
