hi
thank you for your help:

i have a question that deals with finding the direction and magnitude of the net magnetic force on a loop that is next to a wire (the loop is in the wire's magnetic field)

how do i set up a question like this? do i have to integrate since the far side of the loop is not the same distance from the wire as the nearer side of the loop is?

ALSo, do you ignore certain parts of the loop that are not parallel or perpendicular or something??

Thank you very much--- i find physics very confusing
