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. Researchers who ran simulations of these atmospheric ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

A growing “dent” in Earth’s magnetic field over the South Atlantic has expanded dramatically in the last decade, raising concerns about satellite safety and space radiation. A leading magnetic field ...

Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field.

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM spectrum ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Nov 28, 2025, 07:59am EST Map of the strength of the Earth's ...

Scientists at the Florida State University-based National High Magnetic Field Laboratory just created what they claim to be the world’s strongest magnetic field using a toilet paper roll-sized magnet ...

A lab in China has produced the most powerful steady magnetic field in the world. The Steady High Magnetic Field Facility (SHMFF) in Hefei, China, recorded a field strength of 45.22 Tesla (T) on ...

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that ...

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some ...

Scientists have announced that they achieved the highest magnetic field strength ever recorded for an accelerator steering magnet, setting a world record of 14.1 teslas, with the magnet cooled to 4.5 ...
