: "Yes, indeed it does matter who is "writing history." The quotation
above is, in fact, quite wrong."
So the best approach is to take a glance into the original papers.
In Maxwell's model the magnetic lines are like the smoke rings. Nothing
flow
along them.
In Heaviside's model there is the solenoidal flow.
It is not simplification. The both models are quite different.
But the both are a history.
Your radio waves travel in rare plasma. It is interesting that Faraday
predicted it.
S*
they may travel through a rare plasma, but the rare plasma is not
needed for their propagation. they also travel through dense matter
like glass, but the glass is not needed for their propagation.
"The velocity of light through space is about 190,000 miles in a second; the
velocity of electricity is, by the experiments of Wheatstone, shown to be as
great as this,"
For this reason Faraday concluded: " "I suppose we may compare together the
matter of the aether
and ordinary matter (as, for instance, the copper of the wire through which
the electricity is conducted), and consider them as alike in their essential
constitution; i.e. either as both composed of little nuclei, considered in
the abstract as matter"
Everywhere are "nuclei" (electrons).
You simply do not read Faraday.
He also described a dipole: " For suppose two bodies, A B, distant from each
other and under mutual action, and therefore connected by lines of force,
and let us fix our attention upon one resultant of force, having an
invariable direction as regards space; if one of the bodies move in the
least degree right or left, or if its power be shifted for a moment within
the mass (neither of these cases being difficult to realise if A and B be
either electric or magnetic bodies), then an effect equivalent to a lateral
disturbance will take place in the resultant upon which we are fixing our
attention; for, either it will increase in force whilst the neighboring
results are diminishing, or it will fall in force as they are increasing."
" if its power be shifted for a moment within the mass" = if electrons
oscillate in a dipole.
Wimpie mentioned a monopole. Dipole = two monopole.
What does monopole radiate?
In your antennas and in the space are free electrons. We do not need a
mystery TEM..
