Earth’s magnetic field has flipped about 170 times in the last 100 m years, and the next reversal is not a matter of if but when. Far from a cinematic instant catastrophe, a flip would unfold over ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Earth’s magnetic field is known to flip direction with a somewhat unnerving regularity: magnetic north switches to south, and vice versa. The processes that drive this change are poorly understood; ...
