The strange phenomenon can cause Earth's magnetic field to reverse

A repeating phenomenon in the intersection of the core layer and the mantle beneath Africa is threatening to reverse the magnetic poles.

The Earth's magnetic field is weakening at such a fast speed that scientists think the magnetic poles will reverse. New research by scientists shows where the weakest magnetic field is in Africa, in an area called " (SAA), RT reports.

The magnetic field covers the Earth, protecting the planet first and. Without a magnetic field, life is more likely to not exist on the planet. However, this shield is much weaker in the past 160 years and scientists predict it may be in the process of reversing. This means the magnetic pole will change and the compass will point south instead of the north.

The magnetic polarity has happened several times in Earth's history, separated from 200,000 to 300,000 years. About 40,000 years ago, the magnetic field almost reversed before returning to its previous position. SAA stretches from Zimbabwe to Chile, particularly interested by scientists. The magnetic field here is so weak that satellites flying through this area are very vulnerable.

Researchers believe that SAA may be a sign of an imminent polarity but there is little data to prove. However, a new study from the University of Rochester, New York, USA, published in the journal Geophysical Research Letters sheds light on this remarkable phenomenon.

Researchers gathered data from areas in southern Africa and drafted notes on the strength of centuries. They took data from the remains of ancient African clay pieces, dating back to the beginning and end of the Iron Age. The specimens allow them to study magnetic fields in the past by "ancient" methods .

"When you burn clay at very high temperatures, you balance the magnetic minerals and when cooled, they retain a record of the Earth's magnetic field , " said John Tarduno, a research team member. , explain.

Tarduno's group discovered that the school in the area had fluctuated several times in the past 160 years. They argue that SAA is the most recent evidence of a repeating phenomenon in the core of the Earth beneath South Africa affecting the globe.

"We obtained more compelling evidence that an abnormal phenomenon in the intersection of the core layer and the mantle beneath Africa has an important impact on the global magnetic field , " Tarduno concluded.
