1. The problem statement, all variables and given/known data A 14.2 cm - diameter circular loop of wire is placed with the plane of the loop parallel to the uniform magnetic field between the pole pieces of a large magnet. When 3.10 A flows in the coil, the torque on it is 0.135 m N. What is the magnetic field strength? 2. Relevant equations;3. The attempt at a solution Okay, I know that I need to find the value for B, the magnetic field; and that there are a number of equations that I can use. However, Im a bit confused, since torque is given; I know that it will be used in some way. Any help is welcome!
