Earth’s magnetic field has behaved even more dramatically ... Brown said. The last big flip was about 750,000 to 780,000 years ago. During a polar flip, animals that migrate using the magnetic ...

If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere ... disrupting the modern world in a big way. Given ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

"It's a big, chaotic and turbulent ball of molten ... The phenomenon "may be linked to the Earth's history of magnetic pole reversals, which have occurred nearly 200 times over the past 100 ...

Since their relatively recent appearance on the commercial scene, rare-earth magnets have made quite a splash in the public imagination. The amount of magnetic energy packed into these tiny ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells ...

As this material is often conductive, it will likely affect the Earth’s magnetic field, as argued by [Sierra Solter-Hunt] in a pre-publication article. Although the speculation by [Sierra] can ...

Earth's core contains liquid iron which moves around. Iron is magnetic so the liquid iron causes Earth to have a magnetic field. The needle of a compass is a small magnet that can turn.
