Why magnetic pole is moving towards Russia?

Date: 18 May 2020 Tags: Geography & Environment

Issue
Scientists from ESA found an explanation for why the magnetic pole of the Earth performs a rapid motion toward Russia. This phenomenon for several years has haunted professionals from around the world.

 

Background

When the precise position of Earth's magnetic north was located for the first time back in 1831, it was squarely in Canada's corner of the Arctic.

 

Details

  • According to researchers, the observed movement of the North magnetic pole is closer to the Russian Federation can be connected with the stretching of the magnetic field that lies deep beneath the surface of the Blue planet.

  • Experts indicate that the shifts taking place in the flow of the molten material inside the Earth, made adjustments to the nature and effect of the mentioned areas of negative magnetic flux. Visually it can be compared to a tug-of-war.

  • According to the model, over the next few decades, the pole will continue to drift towards Siberia. Moreover, it is unclear whether he will return later to Canada, or movement will occur to the South.

  • Since the 1990s, its movement has quadrupled in speed, to a current rate of between 50 and 60 kilometres a year. In late 2017, the pole's sprint brought it within 390 kilometres (240 miles) of the geographical North Pole.

  • On its current trajectory, we can expect it to be anywhere between 390 and 660 kilometres (240 and 410 miles) further along its journey in ten years, bringing it within a whisker of the northern limits of the East Siberian Sea.

  • The rapid displacement is a concern for navigation systems that rely on pinpoint calculations of the pole's location, forcing the US National Geophysical Data Centre to fast track its usual updates to the World Magnetic Model last year.

  • The pole's heading lines up neatly with two anomalies called negative magnetic fluxes, one deep beneath Canada, and the other below Siberia.

  • These large lobes of magnetism grow and shrink with time, having a profound effect on the magnetic field we perceive on the surface.
