  The complex Lorentz force is introduced and extended to include magnetic
scalar. This scalar is found to be associated with a prevailing magnetic field
permeating the whole space. It also introduce an extra force in Lorentz complex
force. The magnetic scalar is associated with the vacuum energy. The
Proca-Maxwell's massive electrodynamics is derived from the extend
current-density transformations. Proca-Maxwell's theory is found to be
invariant under the extended gauge transformations (current-charge density).
The Lorenz gauge condition is shown to express the photon charge conservation.
Any violation of Lorenz gauge (photon charge) or electronic charge conservation
would lead to spin zero scalar particles. This is manifested in
superconductivity. The total charge comprising the electron and photon is
always conserved. Owing to superconductivity, the photon charge is related to
electron charge by $e_p=\sqrt{\frac{m_p}{m_e}}\,\,e$. Photons inside
superconductors are shown to be massive. It is shown that Maxwell's equations
expressed in complex form are more convenient to study duality transformations.
