1. The problem statement, all variables and given/known data A small loop of wire of radius 1.5 cm is placed at the center of a wire loop with radius 20 cm. The planes of the loops are perpendicular to each other, and a 5.0 -A current flows in each. Estimate the magnitude of the torque the large loop exerts on the smaller one. 3. The attempt at a solution I've pretty much started by finding the magnetic field at the center of the big loop. I'm not sure how to proceed.
