So my first obvious question is, why would you care? If you want to
duplicate the inductor, you already know the inductance, and you can
measure saturation effects and even loss, with some ingenuity.

I could have two inductors that look the same on their outside, but have
radically different inductance values. I could have two inductors that
are of the same inductance but have radically different core material
and size.

if the core has a large air gap ( 1mm), inductance is governed pretty much
by the air gap, and is pretty much independant of the core material.


I'm just trying to get some idea of what makes up the inductor. Turns
of wire is just one of them. Another is what kind of core material is
used. I think that if I know the turns, it will give some idea of the
core material.
