EARTH’S magnetic north pole is moving towards Siberia at such a rapid pace that researchers are baffled.
Unlike geographic north, the magnetic north pole is known for wandering but it’s only recently started shifting dramatically.
Previous studies had suggested that the magnetic north pole of the earth has been moving away from its previous home in the Canadian Arctic towards Siberia at a rate of about 55 kilometres a year in the past two decades.
However, as per the new report released by the National Centers for Environmental Information and the British Geological Survey, it has been learned that movement is still continuing, but at a slower rate of 40 kilometres each year.
The model of the earth’s magnetic north pole has crucial significance in calibrating GPS and other measurements. Even though the north magnetic pole has been drifting since the 1830s, its movement increased over the past few years, and this phenomenon had recently compelled scientists to update the World Magnetic Model which is widely used by civilian navigation systems.
The earth’s magnetic field is the result of the churning of the planet’s iron outer core, that in turn produces a complex north-south magnetic field. However, due to unknown interior dynamics within the planet, the magnetic field is currently going through a weakening stage, and it is resulting in the drift of the magnetic north pole.
Will earth’s magnetic pole shift living beings?
It is still unclear whether the earth’s magnetic north pole which is currently drifting is gearing up for a flip-flop switching north and south, or sometimes, the magnetic field will strengthen again, and it will stop the drifting process.
However, living beings on the earth need not worry, as such magnetic pole shifts had happened in the past without any negative effects on the planet’s biology. But recalibration should be done on navigation devices, as these types of equipment usually make use of the World Magnetic Model to function.
