Question

An electron moves in a circle of radius r = 6.19 × 10-11 m with a speed 2.47 x 106 m/s. Treat the circular path as a current loop with a
constant current equal to the ratio of the electron's charge magnitude to the period of the motion. If the circle lies in a uniform
magnetic field of magnitude B = 6.04 mT, what is the maximum possible magnitude of the torque produced on the loop by the field?
