Kraus characterizes inductors as helices. At one extreme they are
stretched into straifht wires. At the other they collapse into
single
loops.

=====================================

See program SOLNOID3 which calculates inductance of 1-turn loops, via
multi-turn solenoids, to straight wires. With many other parameters
of interest such as temperature rise for a given applied voltage, as
in tank circuits and antenna loading coils.

So far as the author is aware there are no bugs in it. It's been
around and much used for a few years.
