Vigorous' magnetic field oddity spotted over South Atlantic

A long-standing weak spot in Earth's magnetic field is getting weirder, and it may be splitting into two distinct zones of weakness. The South Atlantic Anomaly is a section of Earth's magnetic field between Africa and South America. For decades at least, this region of the magnetic field has gotten weaker and weaker, part of a global trend. According to the European Space Agency (ESA), the global magnetic field has lost 9% of its strength over the past 200 years. The South Atlantic Anomaly seems to be a particular point of change. Now, satellites investigating the anomaly have detected an intensified.......
