A circular coil of 50 turns has a radius of 0.2m and carries a current of 5A. The coil is in a field where the magnetic induction is 0.6 Web/m^2. What is the max torque on the coil? I used the formula for the torque on a coil: r=NBIAcos(theta) I assume that the angle for max torque is 0 my answer is 6pi.. is that right? is it ok to let the angle be 0??
