Earth's magnetic north pole shifts eastward at increasing speed

iflscience.com

Earth's magnetic north pole is moving eastward at an increasing rate. Since the 1830s, it has shifted about 2,250 kilometers from Canada towards Siberia. The movement has accelerated from under 15 kilometers per year to around 50 to 60 kilometers per year since 1990. The south magnetic pole is also drifting eastward over Antarctica. Scientists note that magnetic poles can swap positions every 300,000 years, and the last swap occurred 780,000 years ago, suggesting a potential change could be due. The movement is caused by molten metals in Earth's outer core, which create electric currents and a magnetic field. While the shift has little daily impact, it may require updates to GPS and navigation systems.
