exactly...look at all of the modern technology, that must have a variable magvar built into it.
What really cracks me up is when they rename the runways, and all of the associated charts, equipment, and infrastructure changes.
As a point of reference, that is how they determined seafloor spreading, the magnetic orientations in the rock across the Atlantic, when the poles flip, and according to records, it wobbles for a very short time then flips.
The Sun drives the forces, and just as magnets repel or attract, the Sun and the Earth mag poles do the same.
The Suns mag pole flipped in 2001, and the Earths and been wobbling quite a bit, so scientists look for the mag poles to flip very soon...
and no, the Sun will not rise in the West, the Earth doesnt flip, just the magnetic polarity....
Nasa simulation..
I would hope that you are not using a compass to navigate...
