95% plus of the transmitter or received energy is safely contained

out. All of the feed line center conductor current is pretty well
matched by the same current in the shield. It is the closely coupled
concentric magnetic fields that make coax work so well.


Or, simply put, for ever action, an equal and opposite reaction occurs
... yes, basic physics ... however, what is in question--since the other

Gawd, I am getting hasty in my old age ...

No electrical field can occur without a magnet field, no magnetic field
can occur with out a corresponding electrical component, again, basic
physics; you are attempting to say the magnetic component of the current
on the outside of the braid is NOT SEEN by the center conductor ... that
may be in error ... but, I would be willing to listen how tinned copper
(the braid) is some sort of shield to magnetic fields ...

Geesh, too old, I am telling you ...

Disregard "static fields", however, that is NOT what is in question here
...
