Art, picture a dimensionless point in your mind. Define that point as
an inductance without dimensions, without capacitance, and without
resistance.
There is your "IDEAL inductance" and exists ONLY in the human mind and
certain
computer models. Since it is dimensionless, the current into the point
and the
current out of the point are the same current because they are the same
point
and, of course, the dimensionless point is traversed instantaneously.

Now, without modification, extend that dimensionless concept to a one-foot
diameter, one-foot long bugcatcher coil, wound with 60 feet of
real-world wire.
Assert that the bugcatcher coil has virtually identical characteristics
to that
previous dimensionless point in your mind. Use a computer model's
dimensionless
inductor feature to prove your point.

That's the present "physical arrangement". :-)

There are lots of ways to make inductors, (coils, transmission lines,
meander lines, etc.) but there is only one inductance.
