The magnetic whirl around a wire is a assmption. The clasical EM is
valid only for such assumption.

EM waves in free space, "in" a wire, or in a waveguide,
propagate at the speed of light in the medium. Therefore,
the EM energy is photonic since electrons cannot move
that fast. Even the impulse current in a DC circuit
is photonic. The name "standing wave" is an oxymoron.
If its standing, it's not a wave, by definition.

An analogy might be water flowing through a pipe. One
can send information through the pipe much faster than
the water is flowing.
