The magnetic pole began to move faster.
The National Geographic Society of the United States reports that the movement of the north magnetic pole of the Earth has accelerated again, and now it is moving from Canada towards Russia at a speed of 64 km per year. The South Pole is also moving, but much slower (because it is not a pure dipole).
The movement of the magnetic pole is a normal phenomenon, since the iron core of the planet rotates at high speed and creates a dynamo effect moving the poles.
Periodically, the north and south poles change places ( magnetic field inversions occur). The current phase of migration of the north magnetic pole towards Siberia began in 1904 at a speed of 14 km per year, but since 1989 it has increased dramatically, by 2007 it was 55-60 km per year, and now it has grown even more. While scientists are not ready to say for sure that the pole will cross the territory of mainland Russia, because its direction and speed are highly unpredictable (as history shows, inversion can occur in tens of thousands of years, and in tens of millions of years, scientists have already collected data for the last 150 million years measuring the magnetization of stones).

At the request of the International Shipping Organization ( PDF ), in the coming years, all large vessels must install gyrocompasses, because navigation on a normal compass becomes unreliable in current conditions.
