Current through coils

It looks like various magnitudes that you would find at 2 points along
a standing wave, with various fractions of the wave in the inductor as
frequency changes. In spite of hitting these various magnitude
values, there are still only two phases, 0 or 180 anywhere outside the
coil. In some cases, the standing wave goes through a node, inside
the coil and reverses phase from one end of the coil to the other.
Exactly! Now please explain how the nS delay through a coil
could possibly be measured using a signal that abruptly shifts
fixed phase by 180 degrees every 180 degrees.
The only way I can see to do it is to go outside the coil and look at
how the standing current nodes move. Standing wave phase is with
respect to position, not time.
