Earth's magnetic north pole, which has been wandering faster than expected in recent years, has now crossed the prime meridian.
Magnetic north has been lurching away from its previous home in the Canadian Arctic toward Siberia at a rate of about 34 miles (55 kilometers) a year over the past two decades. The latest model of the Earth's magnetic field, released Dec. 10 by the National Centers for Environmental Information and the British Geological Survey, predicts that this movement will continue, though likely at a slower rate of 25 miles (40 km) each year.
This model is used to calibrate GPS and other navigation measurements.
Earth's magnetic field is produced by the churning of the planet's iron outer core, which produces a complex, but largely north-south magnetic field. For reasons not entirely understood but related to the planet's interior dynamics, the magnetic field is currently undergoing a period of weakening. That's why magnetic north is drifting.
As of February 2019, magnetic north was located at 86.54 N 170.88 E, within the Arctic Ocean, according to the NCEI. (Magnetic south similarly does not line up with geographic south; it was at at 64.13 S 136.02 E off the coast of Antarctica as of February 2019.)
Scientists release a new version of the World Magnetic Model every five years, so this 2020 update was expected. In February 2019, though, they had to release an update ahead of schedule due to the fast clip of magnetic north's movements. The 2020 model shows the "Blackout Zone" around magnetic north where compasses become unreliable and start to fail because of the proximity of true north. The new maps also show magnetic north east of the prime meridian, a boundary the pole crossed in September 2019, according to Newsweek. The prime, or Greenwich, meridian is the meridian that was set as the official marker of zero degrees, zero minutes and zero seconds in 1884;iIt runs through the Royal Observatory at Greenwich in England.
