Abstract

Equilibrium of charge distributed throughout the electron ring interior is a result of electromagnetic self-forces that control the structure and internal motion of charge. The exact distribution of charge density inside the ring-shaped electron is described by equations and graphs. The dimensions of ground-state electrons are obtained from a physical spinning charged ring (SCR) model. The model yields the large radius and small radius of the electron ring. And the model also yields the actual non-anomalous magnetic moment of the electron. Thus, the SCR Model predicts that the diameter of a free electron is finite and physically related to electron properties such as its rest-mass, spin, magnetic moment, line spectra, and wavelength.
