No, that’s just a simple experiment one can do if one wishes, in the lab. Actually such experimental measurements of the growth of the fields and potentials from a sudden source charge are all over, but usually never addressed as “just that” for the purpose of establishing the fields.
He doesn’t mention that you can suddenly produce a dipole (magnetic or
otherwise) at a point in the lab, and with your instruments pre-placed
on a radial line away from that point, you can directly measure the
speed of light flow of those photons pouring from that magnet. Hey! If
they’re sitting still, then the field could never be established in
the first place
