(See thread "Relativistic velocity in the time dimension", post 11)pmb_phy said:.. and is a 4-vector. This is known as the electric field 4-vector. Not to be confused with the electric field 3-vector. There is a magnetic field 4-vector too which is similar to this...
I delved into this some time ago. An interesting source I found in Feynman's Lectures on Physics, volume II, in particular because of his non-standard way of approaching these things. Do you have suggestions for additional sources?
While studying this matter I wondered if the scalar component [tex]\phi[/tex] for the electric potential in the 4-vector for electromagnetic potential [tex](\phi, \vec{A})[/tex] could not simply be regarded a vector potential from the perspective of 4D as a result of the temporal component [tex]\gamma c[/tex] in the 4-velocity vector [tex]\gamma(c,\vec{v})[/tex] for the charge? After all, this temporal velocity component would present the charge as a "current" in the time dimension (a "temporal current" if you wish), which would logically allow the association of a vector potential with it.
