Greg, I'm glad I'm not the only one who thinks modelling
the coil isn't simple. Just a reply if I may on transmission lines...

I think that is only true when the line is terminated in it's Zo at
each end making it a matched line. A piece of coax (for example) that
has any other termination or is shorted or o/c has a high VSWR and is
highly resonant (Y-N)? We had a problem here where a 50 ohm data link
cable had a piece of 75 ohm coax added in by mistake. Reflections and
high VSWR meant the link failed totally. I designed a 1.2:1 line
matching transformer to correct this problem, one inserted at each end
of the 75 ohm cable.
I think your model of a sinusoidal voltage/current distribution is
actually quite accurate.
