"Wheeler's formula is very good at finding the inductance of a coil,
but it is an empirical formula derived from test "results" only. "
Nope. Wheeler's various formulae represent simple numerical
approximations to Nagaoka's formula. The different formulae have
different accuracies at different l/d ratios. Nothing experimental
involved.
