A circular loop of radius .0200 m contains 60 turns of tightly wound wire. If the current in the windings is 0.358 A and a constant magnetic field of 0.259 T makes an angle of 52.0 with a vector perpendicularwith the loop, what torque acts on the loop? Answer in units of N · m.I tried Torque = NABIsin(theta) where N is # of turns, A is radius, I is charge, and B is the magnetic field. It wasn't the right answer.
