1. The problem statement, all variables and given/known data A current carrying wire is bent into a circular loop with radius R and lies in the XY plane. A uniform magnetic field in the +z direction exists through out the plane of the loop. What is the magnetic force exerted on the loop? 2. Relevant equations Fb = I lb sin (theta) 3. The attempt at a solution Since there is no values given and it's all conceptual this is what I got. I'm thinking it's going to be zero because Quadrant 1 and 3 will cancel each other out and quadrant 2 and 4 will cancel out. I'm not sure is correct.
