A number of electron spin models have been put forward to evaluate the values of angular momentum and magnetic moment. Thus the electron cannot be a point particle and it must have different mass density and charge density. However, if electron was a point particle, and the spin arose from certain rotation effect, then its magnetic moment and angular momentum would always obey the classical relation, and the spin magnetic moment of the electron would be half of the correct value. In quantum field theory, electron is regarded as a point particle (bare electron) with a covering of virtual photons. As the electron spin can be derived from Dirac equation, it is often owed to relativistic effect. To see the difficulties arising from regarding electron as a rotating rigid sphere, one may see Refs. However, if we wish to get the spin value based on that hypothesis, the rotational speed of the electron surface would be more than 100 c, which is obviously unreasonable. If the mass of the electron is totally due to electromagnetic origin, then the classical radius of the electron will be the order of 10 −15m. The mass origin and the radius of the electron are long standing problems in classical and modern physics. In addition, the hierarchy problem can be solved with the same hypothesis. Given that the energy of the virtual photon obeys the classical Maxwell-Boltzmann distribution, the self-energy of the electron will be finite. Suppose the probability of virtual photons converting into electron-positron pairs to be 0.00141, the result agrees with that of quantum electrodynamics. In the meanwhile, the anomalous magnetic moment is evaluated based on the wave function of the spinning electron. In the case of the quantum numbers of spin angular momentum and magnetic moment being 1/2 and 1 respectively, their correct values can be obtained. Assuming that the rest energy of the electron originates from the kinetic energy of the virtual particles, the electron spin motion equation and spin wave function can be derived. ![]() It is shown that the classical method cannot derive the correct magnetic moment value. The classical and quantum mechanical methods are used respectively to calculate the electron spin.
