Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – ...

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

Earth spins, shifts, and now… flips? Our planet’s gymnastics routine continues underneath our feet nearly every day, but researchers at the Helmholtz Centre for Geosciences in Germany recently mapped ...

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

Earth’s magnetic field feels steady and dependable, but over geological time it is anything but fixed. The magnetic north and south poles have swapped places many times in the planet’s history in ...

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity ...
