Canada vs Siberia
Libertas:
In the meantime, scientists are working to understand why the magnetic field is changing so dramatically. Geomagnetic pulses, like the one that happened in 2016, might be traced back to ‘hydromagnetic’ waves arising from deep in the core1. And the fast motion of the north magnetic pole could be linked to a high-speed jet of liquid iron beneath Canada2.
The jet seems to be smearing out and weakening the magnetic field beneath Canada, Phil Livermore, a geomagnetist at the University of Leeds, UK, said at the American Geophysical Union meeting. And that means that Canada is essentially losing a magnetic tug-of-war with Siberia.
“The location of the north magnetic pole appears to be governed by two large-scale patches of magnetic field, one beneath Canada and one beneath Siberia,” Livermore says. “The Siberian patch is winning the competition.”

Interesting. Those deviations to account for in old-style compass readings are ridiculously out of date!

You win the same thing as I because that's what I was thinkin'.

There was a movie, maybe "Core", where the poles switched and people with pacemakers all dropped dead. So be careful out there!

Nothing, because it's really Russians, with the help of Trump, who designed a giant sucking machine to suck the magnetic north pole away from North America.
