First measurements taken of South Africa’s Iron Age magnetic field history

28 julio 2015

A team of researchers has for the first time recovered a magnetic field record from ancient minerals for Iron Age southern Africa (between 1000 and 1500 AD). The data, combined with the current weakening of Earth’s magnetic field, suggest that the region of Earth’s core beneath southern Africa may play a special role in reversals of the planet’s magnetic poles.img src=»» height=»1″ width=»1″ alt=»»/
