It seems reasonable that a stand alone coil can be characterised as a
transmission line having a delay that equates to an electrical length in
degrees, radians, wavelengths or a velocity factor. In fact the
inductance calculator at http://hamwaves.com/antennas/inductance.html is
based on that approach and shows the calculated value of Beta.

But, but, but, Owen, the first reference in that web page
is the very Corum IEEE paper that I referenced that has
been completely and totally debunked by most of the gurus
on this newsgroup.
