The location of Earths north magnetic pole appears to be controlled from deep within Earth by 2 competing blobs in the magnetic field. One is under Canada, and the other is under Siberia. The Siberian blob is winning, according to scientists.
You probably know that a compass doesnt point to true north. Earths geographic north pole and magnetic north pole were first recognized as two different places in 1831. Until the early 1990s, the magnetic North Pole was known to lie some 1,000 miles south of true north, in Canada. Yet, as scientists realized, the location of magnetic north was not fixed. Magnetic north was drifting at a rate of up to about 9 miles (15 km) a year. Since the 1990s, however, the drift of Earths magnetic north pole has turned into more of a sprint, scientists say. Its present speed is about 30 to nearly 40 miles a year (50-60 km a year) toward Siberia. And now using satellite measurements scientists in Europe have helped confirm a theory as to why Earths magnetic north pole is drifting so rapidly.

Everything is south of True North...
Every so often I go up near the North Pole and drop a magnet nearby. The location of the North Pole changes soon after. Scientists still have not figured it out.

My war cry was always “Yakutsk!” And I staged from there.
i would summer in Yakutsk...
and i would always try to take the southern hemisphere and take pieces of every other continent.
Yeah...buts what the point?
