A mysterious phenomenon is now affecting our planet, baffling the scientists. According to new research, the Earth’s magnetic field is moving erratically, puzzling geologists. More specifically, Earth’s north magnetic pole moved suddenly and fast from Canada and towards Siberia, dragged by the liquid iron movements in the planet’s core.
Accordingly, the experts are now about to adopt a rare move, as they now have to update the World Magnetic Model which describes the Earth’s magnetic field.
“That was an interesting situation we found ourselves in. What’s happening?” asked Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information.
According to Chulliat, the 2016 geomagnetic pulse beneath South America went on too early after the latest update of the World Magnetic Model in 2015. So, just after the newest update of the model, the Earth’s magnetic field changed.

Also, the movement of the north magnetic pole increased the problem. The Earth’s magnetic field is wandering in unpredictable ways since the first observations James Clark Ross has made in 1831 in the Canadian Arctic. In the mid-1990s, the field speeded up from about 15 km per year to 55 kilometers per year.
In 2018, the north magnetic pole crossed the International Date Line into the Eastern Hemisphere, and now it’s moving towards Siberia. “The fact that the pole is going fast makes this region more prone to large errors,” said Chulliat.
“The location of the north magnetic pole appears to be governed by two large-scale patches of the Earth’s magnetic field, one beneath Canada and one beneath Siberia. The Siberian patch is winning the competition,” also said Phil Livermore, a geomagnetist at the University of Leeds, in the United Kingdom.
Livermore and Chulliat, along with their colleagues, will have a lot of work to do, but not before updating the World Magnetic Model.
