The pole has been the friend of navigators for millennia, beckoning compass needles from virtually every point on the planet. And unlike the geographic north pole, which is fixed, the north magnetic pole has been slowly migrating over time -- moving across the Canadian Arctic toward Russia since 1831.
But its swift pace toward Siberia in recent years at a rate of around 34 miles per year has forced scientists to update the World Magnetic Model -- used by civilian navigation systems, the North Atlantic Treaty Organization, and US and British militaries -- a year ahead of schedule.
...Scientists first noticed the change in 2018 thanks to a "huge amount of satellite data," which showed the pole had gone beyond the model's predicted area, Beggan said.
...There have been a few theories about why the pole's movement has increased in recent years -- from around 6 miles a year between 1900 and 1980 before accelerating to around 24 to 31 miles a year in the past two decades. Some scientists think a jet stream of molten liquid is pushing the north pole, while others have suggested that the south and north magnetic poles are reversing positions."
