  • A giant weak spot in Earthâs magnetic field is now half the size of Europe Earthâs magnetic field is on the move â and one giant weak spot over the Atlantic is getting dramatically bigger. - Date: - February 25, 2026 - Source: - European Space Agency (ESA) - Summary: - Earthâs magnetic shield is shifting in dramatic ways. New data from ESAâs Swarm satellites show that the South Atlantic Anomaly â a vast weak spot in Earthâs magnetic field â has grown by nearly half the size of continental Europe since 2014. Even more striking, a region southwest of Africa has begun weakening even faster in rec
