Earth's magnetic field flipped 42,000 years ago, study shows | Hashem Al-Ghaili

The Moon helps control Earth’s tides, but did you know it might also help fuel our magnetic field? According to a recent study, the Moon’s gravity may act upon the liquid iron in Earth’s core, creating movement which generates the dynamo effect, which is responsible for our magnetic field. This magnetic field shields Earth from harmful radiation, and this means the Moon is likely essential to protecting life on Earth! #Moon #Space #Gravity #Earth | Museum of Science, Boston
