The diagram (see picture) depicts two long horizontal straight parallel wires that are a distance d=20.36cm apart and each carries a current of 3.25A in the same direction, out of the page. What is the magnitude of the magnetic field at a point that is a perpendicular distance r=30.82cm from both wires? While I have "attempted" this problem, i know my attempts are wrong. (having missed 2 days of classes due to illness, i am behind and my homework is due tomorrow). thanks for any help you can give.
