Earth’s magnetic North Pole, which has been moving northward and eastward for nearly 200 years, is now shifting toward Siberia after accelerating to speeds of up to 30 miles per year in the 2000s, though it has recently slowed to 22 miles per year. This movement is caused by changes in Earth’s outer core, where liquid iron creates the magnetic field and shifts the pole as magnetic forces change. Most people won’t notice changes on their compasses, as annual variations are minimal.
