The magnetic north pole on Earth is moving



So far, it was believed that the magnetic north pole is about 1600 kilometers from the geographic North Pole, near the Batter Island, in northern Canada, on Nunavut.

Recent measurements, however, show that it is moving extremely fast from Canada to Siberia. Something that led to investigators being forced to make changes of extreme urgency in the World Magnetic Model. Because this model controls modern navigation.

This is because these sudden changes in the northern magnetic pole can cause changes in the navigation systems used in ships, planes or even in mobile phones.

So, "scientists have launched a new model to represent the change of magnetic field between 2015 and now." This was reported by the National Center for Environmental Information and the National Oceanic Administration.

"For most consumers, under 55 degrees north, there is no real difference," said Sieran Began, a geophysicist from the British Geological Survey, who created the NOAA map.

Moreover, throughout the history of our planet, magnetic poles have not always been as we know them, but they have been inverted several times.

The last time the magnetic poles were turned, it was about 780,000 years ago.

It is believed that the cause may be a change in the interior of the Earth's core. Since there is a hot ocean of iron and nickel in the core of the planet where the movement generates a magnetic field, explained geophysicist Daniel Lathrop of the University of Maryland. The magnetic south, on the other hand, moves at a much slower speed.

Scientists are working to understand why the magnetic field is changing so dramatically. Geomagnetic impulses return to the "hydromagnetic" waves that arise from the deepest part of the nucleus. And the rapid movement of the North Magnetic Pole can be linked to a high-speed liquid jet under Canada.

"The location of the magnetic north pole seems to be regulated by two large magnetic fields, one under Canada and one under Siberia, so the Siberian patch wins the race," said Phil Livermore, a geomagneticist at the University of Leeds, UK.

Scientists believe that the magnetic poles turn every 200,000-300,000 years and more than 700,000 years have passed since the last investment.

Is the Earth as special as we think?
Unlike the fixed geographic North Pole, the magnetic north pole has migrated little by little over time.
