A new material to unearth mysteries of magnetic fields

by William Weir, PHYS.ORG

Journeying to the center of the Earth, a la Jules Verne, won’t be happening anytime soon. A new material made from a liquid metal and magnetic particles, however, could make it much easier for researchers to recreate the powerful forces at the planet’s core.

Earth’s magnetic field surrounds our planet like an invisible force field – protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is continuously changing.

Indeed, our planet’s history includes at least several hundred global magnetic reversals, where north and south magnetic poles swap places. So when’s the next one happening and how will it affect life on Earth? Continue reading Earth’s magnetic poles are set to swap places – and we’re totally unprepared
