If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) ...

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 ...

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

Since the forces that generate our magnetic field are constantly changing, the field itself is also in continual flux, its strength waxing and waning over time. This causes the location of Earth ...

Earth’s magnetic poles are constantly on the move, but they haven’t drifted far enough to actually flip in the modern age. Researchers know that Earth’s poles have flipped in the past ...

The Earth is in a constant state of flux, and changes are constant on its surface and deep within its core. The shifting tectonic plates, climate variations, and even the movement of the magnetic ...

While shifting is not a rare occurrence, the pole is moving both faster and differently than it was before, raising questions about the planet's magnetic field. If the Earth's field is disrupted ...

But it’s more important than you might think. The Earth acts like a giant bar magnet, with a magnetic north and south pole. Confusingly, these are not in the same place as the geographic north ...

The Earth’s magnetic field is detected by species across the animal kingdom — there are even suggestions that some humans unknowingly sense it — using an ability scientists call ...
