So, in other words you agree


Hi Dan,

I use my own words, not other words, and certainly not laden with
artificial constraints and presumptions. If you want to ask a
question without all these drapes, go ahead; it is far simpler, and
consumes less bandwidth.

OK, I will ask it like this:

On an article at http://www.w8ji.com:80/inductor_current_time_delay.htm
the author discusses time delay through an inductor.

Do you agree with the following 2 paragraphs in that article:
"How does the current travel through the inductor so fast?

At first this seems impossible, but the answer is actually quite obvious.
Time-varying current gives rise to time-varying magnetic flux. This magnetic
flux, since conductor spacing is close and the distance very small, links
the starting turn very tightly to the next turn. The rapidly changing
magnetic flux causes charges to move in the next conductor, and the changing
magnetic field couples through all the close spaced turns with very little
time delay. It is this magnetic flux coupling that provides the primary
mechanism for energy transfer through the inductor, and the path is much
shorter than the circuitous and much longer path along the conductor."

The close spacing of the coils reduces the time delays because the current
is "pushed along" faster.

Agree?


Not particularly. You got any more questions?
