This weakening is also causing technical disturbances in some satellites orbiting Earth.
Scientists are using data from the European Space Agency’s Swarm constellation to improve our understanding of this area, which is known as the ‘South Atlantic Anomaly.’
Among other things, Earth’s magnetic field protects humanity from space radiation and super-charged particles emanating from the sun.
It has been speculated whether the current weakening of the field is a sign that
Such events have occurred many times throughout the planet’s history and even though we are long overdue by the average rate at which these reversals take place (roughly every 250 000 years), the intensity dip in the South Atlantic occurring now is well within what is considered normal levels of fluctuations.
The mystery of the origin of the South Atlantic Anomaly has yet to be solved. However, one thing is certain: magnetic field observations from Swarm are providing exciting new insights into the scarcely understood processes of Earth’s interior.
