The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed.

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

The North Pole is a land of extremes. Because of the Earth's tilted axis as it revolves around the sun, sunlight is either constant or not present at all depending on the season, according to ...

So it's a map of the North Pole and adjoining areas, and it was printed in what they call it Oxon, which is the, um, Latinized name for Oxford. So it was printed in England, and it's by Moses Pitt.

Runners are preparing for the Chicago Marathon later this year, but one resident has her sights set much, much further north.

A map showing the movement of the magnetic north pole. The magnetic north pole of Earth moves over time depending on the motion of molten iron in the planet's core.

In the 300 years between 1600 and 1900, scientists estimate that the magnetic North Pole moved about six miles per year. At the beginning of this century, it picked up to about 34 miles per year ...

The magnetic North Pole is moving from Canada toward Siberia. The Earth's magnetic field has slowly changed since the planet's formation. As tectonic plates rise along mid-ocean ridges and meet ...

Scientists are baffled as the North Pole moves increasingly closer to Russia which could eventually play havoc with people's smartphones. "The magnetic pole has been moving very slowly around ...

The magnetic north pole, where compass needles point, is about 1,200 miles south and is where geomagnetic field lines are vertical. Earth’s magnetic north is not static.
