In these many years, we believed that the Earth's magnetic poles are fixed, but were we wrong?
Recently, scientific studies have found that the Earth's magnetic north pole's movement is moving dramatically, and it's true.
Is it due to gravity or something natural phenomena? We don't know yet. But we will discuss some of its details below.
Earth's Magnetic North Pole Movement Is Drifting Dramatically
The Magnetic North Pole is one of the Earth's three poles located at the top of the planet. It is a place situated with geographic pole and geomagnetic pole.
The scientific reports of Earth's magnetic north pole movement drifted on 6 May 2020. The reports suggested that it is moving away from Canada towards Siberia.
A very experienced scientific team from Leeds University believes that it has occurred by the competition of two magnetic 'blobs' on the edge of the Earth's outer core.
Dr. Phil Livermore explains the movement with 'tug of war' effect:
"This change in the pattern of flow has weakened the patch under Canada and ever so slightly increased the strength of the patch under Siberia. This is why the North Pole has left its historic position over the Canadian Arctic and crossed over the International Date Line. Northern Russia is winning the 'tug of war."
Naturally, it means that the change in the flow of molten material in the Earth's interior has changed the strength of the magnetosphere having negative magnetic flux.
Dr. Livermore and his team tried to model the North Magnetic Pole's path through the data from satellites that measured the changing shape of the Earth's magnetic field for over 20 years. Dr. Livermore's team's report further mentioned that the pole would move towards Russia, and it's uncertain whether it will ever locate towards Canada again.

It is said that the magnetic north pole started to move since 2001. By 2019, it moved all the way north and crossed the International Dateline as well as accelerated south towards Siberia.
Reports suggest that the Magnetic North Pole is moving in the speed of 50 to 60 km a year from Canada towards Siberia in Russia. It is the fastest movement recorded since the 1990s.
In 2017, it came to acknowledgment that the magnetic pole came to within a few hundred kilometers of the geographic pole.
