"Earth's north magnetic pole is racing towards Russia at almost 40 miles (64km) per year due to magnetic changes in the planet's core, new research says.
The core is too deep for scientists to detect its magnetic field directly, but researchers can infer the field's movements by tracking how Earth's magnetic field has been changing at the surface and in space.
Now, newly analyzed data suggest that there's a region of rapidly changing magnetism on the core's surface, possibly being created by a mysterious "plume" of magnetism arising from deeper in the core.
And it's this region that could be pulling the magnetic pole away from its long time location in northern Canada, said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France.
Magnetic north, which is the place where compass needles actually point, is near but not exactly in the same place as the geographic north pole. Right now, magnetic north is close to Canada's Ellesmere Island.
The North magnetic pole had moved little from the time that scientists first located it in 1831.
Then in 1904, the pole began shifting north eastward at a steady pace of about nine miles (15km) a year. In 1989 it sped up again, and in 2007 scientists confirmed that the pole is now galloping toward Siberia at 34 to 3 miles (55 to 60 km) a year. A rapidly shifting magnetic pole means that magnetic field maps need to be updated more often to allow compass-users to make the crucial adjustment from magnetic north to true north.
Nobody knows when another change in the core might pop up elsewhere, sending magnetic north wandering in a new direction."
