Current through coils

Hi Tom,
You may be shocked to discover this, but it is possible that my comments
have been reproduced slightly out of context.
At the time, Cecil was still clinging to the notion that if someone did
the measurements properly they could elicit the original phase
information contained in the traveling wave components. In particular,
the space and time coupling represented by the traveling wave function,
cos (kz - wt), was merely hiding. He has since changed his mind, and
unfortunately I seem to have become one of his quotable gurus on this
topic.
A major part of the ongoing debate is the careless use of "phase" as if
it has a single definition. I have counted at least five different uses
in this thread, all correct in their own way, and none interchangeable.
I won't try to explain further. My level of understanding of phase and
such matters is fully satisfactory for me.

Neither you nor Roy have ever made a valid measurement of the
delay through a coil. It is admittedly a difficult measurement
to make directly. Ramo and Whinnery say it "is usually of
prohibitive difficulty".
I think that if Gene believes that, he should redo his math.

You're right, Gene, I'm shocked! shocked! to learn that Cecil might
distort anything anyone might write. I never for a moment, though,
thought there
was anything wrong with your understanding. It was Cecil's understanding
of your understanding that was in doubt.
