On whittaker's analysis of the electromagnetic entity, part IV: longitudinal magnetic flux and time-like potential without vector potential and without electric and magnetic fields

摘要

The condition is defined under which there exists in vacuo Whittaker's longitudinal magnetic flux and a scalar time-like potential, but no vector potential and no electric and magnetic fields. This fundamentally changes the theory of the electromagnetic entity, for example photons emerge straight forwardly from canonical quantization of the scalar time-like potential when no vector potential and no fields are present.
