Earth's magnetic north pole is on the move, prompting updates to the World Magnetic Model (WMM). This crucial tool for navigation ensures that satellites, aircraft, and even smartphone users can ...

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.

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not sound waves. When converted to audio signals, though, these strange ...

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s magnetic north and its chaotic and relatively unpredictable movements.

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 ...

Earth's magnetic field results from a swirling sea of electrically charged molten iron in the planet's outer core. Heat currents and Earth's spin both fuel the movement of this liquid iron.

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...
