Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

NOAA scientists have spent decades tracking how magnetic north wanders, but recent modeling shows a pole moving in ways ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

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 generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature.
