A proton has a magnetic field due to its spin on its axis. The field is similar to that
Chapter 22, Problem 47(choose chapter or problem)
A proton has a magnetic field due to its spin on its axis. The field is similar to that created by a circular current loop 0.6501015 m in radius with a current of 1.05104 A (no kidding). Find the maximum torque on a proton in a 2.50-T field. (This is a significant torque on a small particle.)
