It's shifted in recent years away from Canada towards Siberia.
And this rapid movement has required more frequent updates to navigation systems, including those that operate the mapping functions in smartphones.
A team, led from Leeds University, says the behaviour is explained by the competition of two magnetic "blobs" on the edge of the Earth's outer core.
Changes in the flow of molten material in the planet's interior have altered the strength of the above regions of negative magnetic flux.
