Expressions for the normal and the anomalous electron magnetic moments. The hypothetical electron carted charge propelling engine.

This paper makes use of the Planck constant based definition of the Bohr magneton expression and the standard derivation of the magnetic moment of a point-like electron orbiting on a circle with a radius equal to its Compton wavelength. This illustrates the wave-like nature of the normal electron magnetic moment. Additionally, an analytical expression for the so-called electron anomalous magnetic moment is derived by supposing a non-concentric electron charge distribution which give rise to a current circuit with a radius r c of approximately 0.4478 (fm) inferred from well-established experimental data; this magnetic moment has instead a particle-like behavior. A possible electron spin self-propelling engine based on a pair of shear forces created by a built-in charge-dipole interaction. Finally, a minimalist Planck constant energy-frequency interpretation is disclosed.
