Magnetic North Pole’s «Pretty Fast» Moving to Russia’s Siberia
By Staff, News Agencies
The US National Oceanic and Atmospheric Administration tends to update the location of the magnetic north pole every five years, but the latest update came nearly a year ahead of schedule because the pole is moving so quickly.
Earth's magnetic north pole — the north that your compass points toward — is leaving the Canadian Arctic and moving towards Russia's snowy Siberia at a rate of more than 55 kilometers (34 miles) per year, according to an update by the US National Oceanic and Atmospheric Administration and the British Geological Survey.
In general, the World Magnetic Model (WMM) is updated at five-year intervals to ensure modern navigation keeps up with the changes in the Earth’s magnetic field.
However, the latest update came nearly a year ahead of schedule because of the pole's faster movement, something that was confirmed by University of Colorado geophysicist Arnaud Chulliat, lead author of the newly-issued WMM.
According to him, the current movement of the magnetic north pole "is pretty fast".
Earlier, the Nature journal cited Phil Livermore, a geomagnetism at the UK-based University of Leeds, as saying that the location of the magnetic north pole may be "governed by two large-scale patches of magnetic field" which are located beneath Canada and Siberia.
"The Siberian patch is winning the competition", he pointed out.
The magnetic field is generated by a molten core of iron, nickel and other metals deep inside the Earth, resulting in huge electrical currents to produce a gigantic field.
