Earth's North Magnetic Pole Racing Towards Russia Due to Core Flux 'A new research has determined that Earth's north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year due to magnetic changes in the planet's core. The core is too deep for scientists to directly detect its magnetic field. But researchers can infer the field's movements by tracking how Earth's magnetic field has been changing at the surface and in space. Now, according to a report in National Geographic News, newly analyzed data suggest that there's a region of rapidly changing magnetism on the core's surface, possibly being created by a mysterious 'plume' of magnetism arising from deeper in the core.'
