The magnetic north pole of the Earth is moving rapidly towards Siberia, and can cause navigation systems to become unbalanced. This is the reason.
The Earth map could become unbalanced in smartphones and navigation systems, since the magnetic north pole is moving towards Siberia very quickly. The pole has always been marked by the compass needles helping navigators and travelers all over the planet, but now it moves quickly every year towards Siberia.
Unlike the fixed geographic north pole, the magnetic north pole has been moving little by little, through the Canadian Arctic towards Russia since 1831. Thus, in recent years it has advanced at a very fast pace towards Siberia, around 54 km per year what has made the scientific area have had to update the Global Magnetic Model used by the civil navigation systems, by the North Atlantic Treaty Organization and the military a year earlier than expected.
“Due to unplanned variations in the Arctic region, scientists have launched a new model to represent the change of the magnetic field between 2015 and now,” they have explained from the National Center for Environmental and Environmental Information of the National Oceanic and Atmospheric Administration.
Normally this model is updated every 5 years, and the last time it was updated was in 2015. But the “off-cycle update […] will guarantee safe navigation for military applications, commercial airlines, search and rescue operations, and other operations. around the North Pole, “they explained from the agency.
Ciaran Beggan, geophysicist of the British Geological Survey, who creates the map with the National Oceanic Atmosphere Administration (NOAA), has stated that “for most users below 55 degrees north, there is no real difference.” That is, for civilian purposes the difference is less than for the army or other strategic maps.
This drift is caused by processes in the depths of the planet, according to Beggan. The Earth’s magnetic field is created in its liquid outer core, composed of liquid iron and nickel. “As it flows, it creates an electronic current and that current forms a magnetic field, which travels with the dripping hot core”, says Beggan.
Other scientists think that it is a jet stream of molten liquid that is pushing the north pole, and others that the magnetic poles of the south and north are reversing positions.
“It’s an unusual behavior in historical terms, but by geological scales it’s not unusual. The magnetic field changes continuously, but in part it is due to its natural behavior, “explained Beggan, stressing that there is nothing to worry about.
