The magnetic fields are more than a thousand times stronger than the magnetic field used in MRI machines.

Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a ...

Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of years. Using ancient magnetic records and advanced simulations, scientists ...

The magnetized rocks of Earth's crust and mantle, also known as the upper lithosphere, accounts for generating 6 percent of the planets magnetic field. Data from the European Space Agency's Swarm ...

Simulations suggest that two enormous masses of hot rock have been involved in generating Earth’s magnetic field and giving it an irregular shape ...

Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better understand this mechanism, the team led by Argovia-Professor Martino Poggio from ...

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

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.
