A photon seems to consist of a (+) charge and
a (-) charge, because "pair-production" is always
possible since,

Photon + photon => Positron + Electron + photon.

(That converts energy to mass).

Very simply an Electric field is really a relation like

(-) =======>(+)
E

with E being an Electric Field vector.

The magnetic part of the photon appears when
the photon is measured (annilihated) in an
antenna for example, as the E-field vector
encounters stationary matter and induces a
Magnetic Field at the speed of light.

There does not seem to be any concensus of
what a "flying" photon is between emission
and absorption, but what happens at each of
those events is moderatedly understood.

Anyway it seems quite reasonable to consider
a photon as a pair of charges.
