Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...

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

Welcome to Part 1 of our series on vector magnetic fields in dipole–dipole interactions! In this tutorial, we break down the fundamentals of calculating magnetic fields generated by interacting ...

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

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

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

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

A team of geologists found for the first time evidence linking regions of low seismic velocity and the shape of the Earth’s magnetic field.

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

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 ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Scientists discover 97-million-year-old magnetic fossils that reveal how ancient animals used Earth’s magnetic field as a ...
