in which the planet’s north and south magnetic poles swap places. While such an event is not expected to happen any time soon, they have occurred periodically throughout Earth’s history—the last ...

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.

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.

Earth’s magnetic field has behaved even more dramatically in the past, with the magnetosphere weakening so much that its polarity reversed. This flips the magnetic north and south poles ...

And as the iron and nickel inside our planet shift, so does Earth's magnetic field, meaning the North (and South) Poles are also constantly on the move. If you're using a compass or a GPS system, ...

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. Like an anchorless buoy ...

Sir James Clark Ross discovered magnetic north pole in 1831 in northern Canada. British scientists have recently revealed that Earth's magnetic ... 1,609 kilometres south of the north pole.
