Do you know where this explanation might be found?

Looks like Reg originated this thread.

"Every coil has length. Both L and C are distributed. Therefore the
coil behaves as a transmission line. There are standing waves. Current
and voltage both vary with length."

And on March 9:

"The whole thing could be summarised in one short sentence -

'Coils are distributed transmission lines.'

The same general equations apply to coils of all dimensions, for any
number of turns, at all frequencies, in all applications. There's no
need to unnecessarily complicate things by artificially dividing them
into lumped and other varieties."
