Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not ...

ESA’s Swarm satellite mission has discovered a mysterious magnetic wave that "oscillates every seven years and propagates westward at up to 1500 kilometers (932 mi.) a year." Credit: ESA ...

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 ...

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 ...

As seawater ripples over our planet's magnetic field, it generates weak electric ... measurements of magnetic signals from Earth. Activity dies down during the solar minimum, making it easier ...

of Earth. That's higher than the orbit where you'll find geostationary satellites, but it's still close enough to the planet that the magnetic field is neat and orderly, more like a bar magnet.
