  This communication is devoted to a brief historical framework and to a
comprehensive critical discussion concerning foundational issues of
Electrodynamics. Attention is especially focused on the events which, about the
end of XIX century, led to the notion of Lorentz force, still today ubiquitous
in literature on Electrodynamics. Is this a noteworthy instance of a rule
which, generated by an improper simplification of Maxwell-JJ Thomson
formulation, is in fact physically untenable but, this notwithstanding, highly
successful. Modelling of electromagnetic fields and fluxes in spacetime
respectively as even and odd spatial differential forms and the formulation of
induction laws by means of exterior and Lie derivatives, make their covariance
manifest under any smooth spacetime transformations, contrary to the usual
affirmation in literature which confines this property to relativistic
frame-changes. A remarkable consequence is that there is no entanglement
between electric and magnetic fields and fluxes under special relativity
transformations. In particular, relativistic support to Lorentz force rule is
thus deactivated. For translational motions of charged bodies immersed in a
uniform and constant magnetic field, the induced electric field in such a
frame, is equal to one half the Lorentz force term. The qualitative successful
application of the Lorentz force rule to experimental evidence of special
observers is therefore explained.
