The magnetic field is important for our planet as it protects us from the Sun's charged particles and cosmic radiation, the ESA said while adding that the area where this phenomenon is taking place has also moved expanded and "shifted westward at a pace of around 20 kilometres per year". "However, one thing is certain: magnetic field observations from Swarm are providing exciting new insights into the scarcely understood processes of Earth's interior".
Earth's magnetic field is gradually weakening in an area that stretches from Africa to South America, and scientists who are trying to understand why.
"The new, eastern minimum of the South Atlantic Anomaly has appeared over the last decade and in recent years is [thriving]", Jürgen Matzka from the German Research Center for Geosciences said. A large area known as the South Atlantic Anomaly between Africa and Latin America has recorded a rapid decline there.
Earth`s magnetic field weakens; satellites and spacecrafts malfunction
The European space agency has been analyzing the magnetic field since three 7 years and the mission comprises three identical satellites that give information about the high-quality measurements of field at different orbital planes.
One most speculated reason behind this is that there is a chance that the time for Earth's pole reversal is coming near. This is when the north and south poles swap positions, and that was the last time it occurred 780,000 years ago.
In another statement, the ESA has said that the surface magnetic field has lost around 9 per cent of its strength across the planet over the last 200 years.More news: Mika Brzezinski calls Donald Trump 'sick' over murder conspiracy theory
The ESA stated that it would continue to monitor the weakening magnetic field with its Swarm satellites.
However, the team found that a center of limited strength has developed southwest of Africa in just the last five years. Researchers believe that this may mean that the anomaly may divide into two different cells. While this flip will not occur immediately or suddenly, and will happen over centuries, there would be multiple north and south magnetic poles during this period, all around the planet. New studies indicate that the South-West of this zone there is another anomaly that does not fit the generally accepted theory of formation of Earth's magnetic field.
This weakening is also causing technical disturbances in some satellites orbiting Earth.More news: Joe Biden wins Hawaii Democratic primary
