Solving the Mystery of Flip-Flopping Magnetic Fields: How New Research is Shedding Light on a Cosmic Enigma
Recently, scientists have discovered a hint of a solution to a long-standing mystery in physics: why do Earth’s magnetic fields “flip-flop” every few hundred thousand years? This phenomenon, known as geomagnetic reversals, has puzzled researchers for over a century. Now, a new study suggests that it may be due to a phenomenon called “dynamo reversals” – the flipping of the Earth’s magnetic field due to changes in the flow of molten iron in its core. The findings, published in the journal Nature Communications, could help us better understand the history and future of our planet’s magnetic field.
