Current through coils

The measurement looks good to me. The phase is exactly what EZNEC
predicts -- constant along the wire. The ratio in magnitudes we'd expect
depends on the positions along the wire, not just the spacing.
We are not talking about the magnitude measurements right now.
We are talking about the phase measurements. What good does
it do to use a signal, whose phase is fixed, to measure the phase
shift through a coil or through a wire.
The phase is constant along the wire with or without the presence
of a coil. Why then is a phase shift of zero on both sides of the
coil surprising? And of what importance is that measurement?
