We contemplate a semi-classical mechanics to obtain the spin-orbit interaction energy in an easy method for example the hydrogen atom. The energy of the interaction ∆E can be evaluated in the rest frame of the electron about which the nucleus moves in a circular orbit and the electron is affected situated within a current loop. The interface energy ∆E is produced by the coupling of the screwed up electric dipole due to the electric field En of the core. We point out the presence of an additional force exerted on a spinning electron due to the appearance of its electric dipole moment in the rest frame of the nucleus. After studying the motions of the electron spin and orbital angular moments, it is obtained that the total angular momentum averaged over the orbit is not a constant of the motion in the Thomas Precession. Considering during the spin flip transition the radius of the electron’s orbit is constant. Our model predicts that the energy of the system changes by the factor ½ budding in nature as a consequence of equilibrium and the variation of the kinetic energy of the electron. The orbit radius for immobile, total angular momentum for the circular orbit system including nonzero orbit angular momentum is the radius of the Bohr model in the ground states.
