An electron moves in a circle of radius $r=4.06\times 10^{-11}\mathrm{m}$ with a speed $3.16\times 10^6\mathrm{m}/\mathrm{s}$. 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 $B=6.53\mathrm{mT}$, what is the maximum possible magnitude of the torque produced on the loop by the field? Number Units
