Scientists have developed a theory to explain the movement of the north magnetic pole

Scientists have developed a theory to explain the movement of the north magnetic pole. More precisely, he is moving from Canada to Russia. Researchers write about this in their article in the journal Nature Geoscience.

Earth’s North Magnetic Pole was first discovered by a researcher named James Clark Ross back in the 1830s. At that time, the pole was located on the territory of Nunavut in Canada. Since then, scientists have tracked its movement, which until recently was very slow. But then, in the 1990s, the pole began to pick up speed, moving from Canada to Siberia. The movement of the pole causes changes in navigation systems and smartphones that use its location as a focal point. Researchers came up with, as they believe, an explanation of the reasons for the movement of the pole and why it began to move faster.

Researchers suggest that at the boundary of the core and mantle there are two large areas of negative magnetic flux. They also suggest that changes in the flow of molten metal in the core lead to changes in magnetic flux in the “petals”. The position of the pole is determined by the strength of the two “petals” of the field – when one gains strength, the other loses it, as a result of which the pole moves toward a stronger direction. The result is a constant tug of war between two lobes. Thus, the current movement is due to the fact that one of the shares is gaining the upper hand.

Researchers developed their theory after studying satellite data collected over 20 years. After that, they created a model that corresponded to the historical movement of the pole, and used it to predict the future path. He showed that the pole will continue to move towards Russia at its current fast pace, and then slow down – ultimately it will remain in Siberia. The model was unable to provide any estimates for a more distant future.
