The rapid motion of the Earth's northern magnetic pole prompted researchers to publish an early, unprecedented update of the model, which helps in the movement of ships, aircraft and submarines in the Arctic. Indicators of compasses point to Magnetic North Pole, A point unexpectedly crawled from the coast of northern Canada, a century ago to the mid-Arctic towards Russia.
"The magnetic pole moves about 50 kilometers a year and did not move much between 1900 and 1980, but it has really accelerated in the last 40 years," said researcher Seiran Began of the British Geological Survey in Edinburgh.
He explained that the next update of the "Global Magnetic Model", which is published every five years scheduled in 2020, but the US Army requested an early update, where the Institute runs the model, in collaboration with the US National Oceanic andAtmosphere.
Bagnan said that the movement of the magnetic pole affects navigation, especially in the Arctic Ocean, using NATO, the US and British armies, and civilian navigational bodies. Scientists say the speed of the magnetic pole is caused by unexpected changes in the molten iron mass In the ground.
"The magnetic pole moves more rapidly, making the area more susceptible to major navigation errors," said Arnoldo Schulia, a researcher at the University of Colorado, in a statement to Nature.
