Cause Of Earth's Collapsing Magnetic Field Hinted At In Destroyed African Artifacts

Back in January, a spike in interest regarding Earth’s magnetic field – and whether it’s about to flip or not – occurred. Despite a significant weakening of its magnetic field strength in recent decades, there’s no indication that it’s “about†to flip, and even if it did, the consequences of a geomagnetic reversal would likely not be as apocalyptic as some may claim.
Saying that, there’s plenty about the planet’s magnetic field that we know fairly little about, including its weak spot, the South Atlantic Anomaly (SAA), which extends from Zimbabwe to Chile. Fortunately, a new paper in Geophysical Research Letters shines some light on that with a tale that extends back, rather appropriately, to the Iron Age.
