The Earth’s magnetic field is weakening between Africa and South America, causing problems for spacecraft and satellites, scientists with the European Space Agency (ESA) have said.

Researchers noted that there is an anomaly in the South Atlantic that has grown in recent years. Data from the ESA’s Swarm constellation of satellites showed that the magnetic field’s strength in the area dropped by 8 percent between 1970 and 2020.
