A Hydrogen atom can be thought of as a positive nucleus with a negatively charged electron, orbiting around it in a circular orbit of radius 5x10-11 m. This orbiting electron can be thought of as a current. Since the electron zips around 7x1015 times per second, and has a charge of 1.6x10-19 C, this amounts to a current of 1x10-3 Amps or 1 mA. What is the magnetic field at the center of the atom, produced by this current?
