Scientists find that the magnetic north pole is moving faster than before. And soon, geographic and magnetic north will be aligned. According to researchers at the University of Leeds, the movements of this magnetic north are directly linked to the random flow of molten iron in the heart of our planet
There are three different norths, either geographic north which is the point of convergence of longitudes and which does not move, magnetic north which moves chaotically and the third, that of the maps which does not really exist and is only used. to navigation.
The 3 north are aligning
A study recently published in the journal Nature explains that the theory of a group of researchers from the University of Leeds, led by Professor Livermore, would be that the movements of this magnetic north would be directly linked to the random flow of iron melting at the heart of our planet. The rare movements of the north magnetic have consequences on the surface of the Earth.
According to these experts, moving just a few millimeters of iron in the core could translate to several kilometers on the surface.
Today, this magnetic north is at the level of Canada and is approaching Siberia more quickly than before. If this displacement was previously 10 km per year, today it would be around 50 km per year and the geographic and magnetic north will soon be aligned.
If the movement of magnetic north is not yet fully understood, its trajectory is already known. In a few days, it will cross the other side of the Greenwich meridian before leaving the English coast by 2025, according to the dedicated monitoring organization, Ordnance Survey.
