Scientists Uncover Rapid Expansion of Earth's Magnetic Field Weak Spot

Scientists have revealed that a weak spot in Earths magnetic field, known as the South Atlantic Anomaly, is rapidly expanding and shifting toward Africa, posing potential challenges for technology and navigation.

• The South Atlantic Anomaly, a notable weak spot in Earths magnetic field, has expanded by nearly twice the size of Texas since 2014, increasing by up to 25%.
• This region is currently moving about 14 miles west each year, with its trajectory headed towards Africa, which may affect satellite operations and other technologies.
• The findings were released in a study by the European Space Agency, indicating that turbulent flows of molten iron in the Earths core drive the changes in the magnetic field.
