It seems that Earth’s magnetic field is weakening and changing at the moment. The magnetic North is moving towards Siberia and South Atlantic Anomaly weakening the Earth’s magnetic field. There is some fear that the weakening is causing technical problems for satellites and could have other effects.

Earth’s magnetic field has been weakening across a wide stretch of area for reasons unknown. Scientists have found the magnetic field from Africa to South America to be gradually weakening.
Earth’s magnetic field is weakening, which could affect satellites and spacecraft, caution scientists
The magnetic field of the Earth between Africa and South America is weakening, causing problems for satellites and spacecraft.
The phenomenon has been dubbed as the South Atlantic Anomaly by scientists, who’ve been studying the occurrence, which has grown considerably in recent years.
The data gathered by the European Space Agency’s swarm of satellites reveals that the area of the anomaly dropped in strength by over 8 per cent between 1970 and 2020.
One of the possible explanations for this could be a shift in the Earth’s magnetic field, whereby the North Pole and the South Pole switch places as the field reverses.
This reversal last happened 7.8 lakh years ago, with scientists believing that a shift is long overdue. These reversals usually happen at an interval of 250,000 years.
If a reversal takes place, the repercussions could be significant and could cause major issues for telecommunications and satellite systems.

A possible explanation for the Earth’s North magnetic pole moving toward Russia
A trio of researchers, two with the University of Leeds, the other the Technical University of Denmark, has developed a theory to explain why Earth’s north magnetic pole has been drifting from Canada to Russia.
