The North Magnetic Pole (the centermost point at the top of Earth) has been moving gradually since it was first documented in the 1830s.
A new study published in Nature Geoscience journal says that the changes in North Pole’s location occur due to the movement of molten material in Earth’s interior.
Therefore, this event has caused a massive shift in the planet’s magnetic field.
The current direction of the pole’s movement is impacted by a “blip in the pattern” of the flow inside the planet’s interior.
Scientists believe the blip happened somewhere between 1970 and 1999.
Hence, the Canadian field of the North Pole has become elongated and weaker.
Later, the North Pole’s location moved quickly toward a magnetic field located under Siberia.
Our northern magnetic pole is run by these two blobs or patches.
These patches have kept the North Pole’s location in a constant state.
This condition doesn’t change the physical location of the North Pole, but it still massively affects the Earth’s magnetic field.
A magnetic field is responsible for protecting the planet against solar energy from storms and keeping the Earth’s rotation in order.
Besides, it’s also important for navigation systems like compass and GPS.
Scientists finally understand why the North Magnetic Pole is moving, and they are going to reveal more.
