1. The problem statement, all variables and given/known data A circular loop of wire, of radius r, carries current I. It is placed in a magnetic field B whose straight lines seem to diverge from a point a distance d below the ring on its axis. (That is, the field makes an angle θ with the loop at all points, where tan(θ) = r/d.) Determine the force F on the loop. Express your answer in terms of the given quantities. 2. Relevant equations F = I*L*B*sinθ 3. The attempt at a solution Not sure how to approach this.
