Ancient rocks show Earth’s magnetic field followed deep heat patterns inside the planet for hundreds of millions of years.

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to the creation of a planet’s magnetic fields, which protect the entire planet ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

In the late 1800s, the French naturalist Camille Viguier proposed an idea that would be dismissed and forgotten for more than a century. He speculated that birds and other animals could navigate with ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth's magnetic field is like an invisible shield that protects our planet from solar and cosmic radiation. While it might not be ...

Scientists are mapping the Milky Way galaxy’s invisible magnetic field, revealing how it holds the galaxy together and ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...
