Discover how a rotating coil placed in a magnetic field generates an induced EMF. This video explains the core physics behind electromagnetic induction, showing how motion, magnetic flux, and ...

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

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 ...

Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Oct 23, 2025, 12:48pm EDT Oct 23, 2025, 01:42pm EDT Illustration ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...

We have a suite of incredibly advanced, complex instruments to study the weather on Earth. Space weather isn’t any less complicated—quite the opposite, in fact—and so one would think that the measures ...

Under the right conditions, superconducting magnets allow electricity to flow essentially undisturbed, producing intense magnetic fields for a variety of uses, including nuclear fusion experiments.

Abstract: Short primary single-sided linear induction motor (SP-SLIM) exhibits promising potential in maglev rail transit and other fields. However, due to the magnetic field distortion caused by the ...

Mixing of particles under a 40 G, 10 Hz rotating magnetic field, with monomers remaining in a gas-like phase. Credit: Proceedings of the National Academy of Sciences (2025). DOI: ...
