Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, ...

Sea turtles navigate using Earth's magnetic field like a GPS. Scientists found they learn and remember magnetic locations.

This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and more.

Isua Formation. These results provide the oldest estimate of the strength of Earth’s magnetic field derived from whole rock samples, which provide a more accurate and reliable assessment than ...

As well as a few temporary reversals, the Earth's magnetic field ... are not so simple, and the magnetic field can weaken to as little as 10 percent of the strength we are used to.

No one knows why, but Beggan said it’s probably linked to some pockets of the magnetic field getting stronger and others weakening. He said the overall strength of the Earth’s magnetic field ...

Would a dramatic change in the Earth's magnetic ... use the magnetic field to orient themselves and find their way around. Could they withstand a significant dwindling of the field's strength ...

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.

No one knows why, but Beggan said it’s probably linked to some pockets of the magnetic field getting stronger and others weakening. He said the overall strength of the Earth’s magnetic field ...

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 ...
