Earth’s north magnetic pole is moving at a fast pace from the Canadian Arctic toward Siberia, the Washington Post has reported. The movement of Earth’s northern magnetic pole has forced NCEI’s scientists to update the World Magnetic Model (WMM) in the middle of the cycle. It is said to be moving about 34 miles (55 kilometres) every year. It had crossed the international date line in 2017. The Earth’s north magnetic pole is stated to have left the Canadian Arctic to move slowly moving towards Siberia.
The fast movement has made the US National Oceanic and Atmospheric Administration and the United Kingdom to update the location of the magnetic north pole early. Otherwise, the update generally used to happen every five years in December. The reason behind the rapid movement is stated to be turbulence in Earth’s liquid outer core. On the other hand, the magnetic south pole is moving far slower than the north.
The shift in the Earth’s north magnetic pole may pose problems to many who are dependent on the magnetic north for navigations. The military, NASA, Federal Aviation Administration, and U.S. Forest Service, all use the magnetic north pole for navigation and parachute drops. Airport runway names are also based on the navigation provided by Earth’s magnetic north pole.
University of Colorado geophysicist Arnaud Chulliat, lead author of World Magnetic Model said, “The constant shift is a problem for compasses in smartphones and some consumer electronics. Aeroplanes and boats also rely on magnetic north, usually as backup navigation. GPS isn’t affected because it’s satellite-based. He further added, “The movement of the magnetic north pole is pretty fast.”
