GFCI curious question

The primary cause of imbalance between line and neutral (that aren't actual faults) is usually capacitive not magnetic. EMI filters have small line to ground capacitors which is one cause. Most inrush happens on the line and neutral at the same time. A coil doesn't delay current going in one end from when it comes out the other end of it which seems to be what you are saying.
In EE we called this ELI the ICE man (as a remembering tool).

Voltage (E) will lead the current (I) in an inductive (L) circuit. Current will lead the voltage in a capacitive circuit (C).

Thanks makes sence, would that hold true for a coil resisting the sudden change in current due to the magnetic field?
An inductor does oppose changes in current but at all times the current going in one lead equals the current going out the other end (to be completely technically correct that is except for current through the capacitance to ground which is usually small and more of an effect at high frequencies - at 60 Hz that is usually negligible.)

That is all true but not the effect I was referring to. Those are line to line effects. What trips GFCI is line to ground current which creates a difference in the two line currents.

I was going to dive deeper into this, but this is a bit technical for the garage forum. Thanks for the reply's Innovate1 and slappywhite.
