1. The problem statement, all variables and given/known data The problem is shown in the link below: http://postimage.org/image/do2b7xz0b/ [Broken] 2. Relevant equations Biot-Savart Law's and dF=Idl x B 3. The attempt at a solution My attempt is really just a mess. I essentially want to break it up into 2 segments. (1) Being the straight horizontal segment from -w to w and (2) the semi-oval segment. For the straight segment, I get dl x B to be ydx*z_hat and when I take the integrals in the equation dF=Idl x B, I get a Force of 2wIy*z_hat and since y=0 all along this point I get a Force of 0 due to the line segment at the origin. As for the oval segment I'm probably only correct as far as y=h-x^2 is what needs to be integrated. Any help would be appreciated!
