Fields Within the Atom. In the Bohr model of the hydrogen atom the electron moves in a circular orbit of radius 5.3 X 10-11 m with a speed of 2.2 X 106 m/s. If we are viewing the atom in such a way that the electron's orbit is in the plane of the paper with the electron moving clockwise. Find the magnitude and direction of the electric and magnetic fields that the electron produces at the location of the nucleus (treated as a point).
