The rapid and unstoppable displacement of the northern magnetic pole requires the early release of a new Earth's magnetic field for military and civilian navigation in the Arctic. The partial shutdown of the federal government will delay the release of this model from January 15 to at least January 30, despite the US military announcing the upgrade ahead of schedule.
Nobody is quite sure why the change has accelerated or why the field has not moved so much in recent times after Nature has grown.
The predecessor model of the magnetic field was released in 2015 and updates were scheduled for 5-year intervals. However, the changes are massive enough for military and civilian shipping ̵
This update does not affect GPS receivers that do not rely on the magnetic north pole. Instead, a receiver receives signals from multiple satellites for which the exact position in orbit is known, and uses trilateration (the intersection of its signals) to determine a location. However, satellite orbits are optimized for reception in the most populated parts of the world, and other factors reduce GPS accuracy and reception in the Arctic.
The magnetic north pole was never a fixed point, but the northern apex compass magnets inherently have indicated that they have accelerated their movements over the last 40 years due to movements recorded in the early decades. (The geographic North Pole and the Magnetic North Pole have no special relationship: the former is fixed by cartographers.)
Measured for the first time in 1831 in the Canadian Arctic, the pole moved slowly north. In the 1990s, the pace of change accelerated from about 10 miles per year to 30 miles per year. This has resulted in a total displacement of 600 miles in 150 years. It is now in the Arctic Ocean and is heading towards Siberia.
The liquid core of the earth contributes most to the magnetic field of the planet. As it turns and flows, the field around the world changes and the tip that identifies the North Pole.
