Chapter 20, Problem 37P

* Electron current and magnetic field in H atom In a simplified model of the hydrogen atom, an electron moves with a speed of $\text{1}\text{.09 }\times {\text{ 10}}^{\text{6}}\text{m/s}$ in a circular orbit with a radius of $\text{2}\text{.12 }\times {\text{ 10}}^{\text{-10}}\text{m}$. (a) Determine the time interval for one trip around the circle. (b) Determine the current corresponding to the electron's motion. (c) Determine the magnetic field at the center of the circular orbit and the magnetic moment of the atom.
