The magnetic North Pole is shifting at an ever-increasing rate compared to when records of its course were first kept in the 16th century, according to experts in geomagnetism. It is moving at a rate of 50 kilometers a year across the Arctic region, to be exact. Meanwhile the magnetic South Pole “has stayed almost stationary for decades.”
The magnetic North Pole is the peripatetic point on the Earth’s surface where its magnetic field, created by molten iron churning deep within the planet’s core, points directly downward.
But why is this so important?
Together with satellite positioning data, the model underpins modern navigation, and frequent revisions are essential so operators can reconcile magnetic sensors and compass readings with geographic reality.
