1. The problem statement, all variables and given/known data A wire is formed into a circle having a radius of .02m and placed in a uniform magnetic field of 1*10^-4. A current of 5A passes through the wire. What is the range of potential energy the wire possess for different orientations? 2. Relevant equations torque=BIA 3. The attempt at a solution The answer is 2BIA. However, I am not sure how to relate torque to potential energy in this scenario.
