This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

A newly discovered mechanism known as microtube implosion could make it possible to generate magnetic fields 1000 times stronger than any yet seen in the laboratory. According to the researchers who ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those ...

Researchers have discovered a novel mechanism called a 'microtube implosion,' demonstrating the generation of megatesla-order magnetic fields, which is three orders of magnitude higher than those ever ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

A recent study published inScience Advances reveals that a temporary collapse of Earth’s magnetic field, known as the Laschamps Excursion, had profound effects on early humans. Drawing from ...

Researchers used hundreds of thousands of computer simulations to examine the remnants of these ancient magnetic fields, which still reside within the "cosmic web" billions of years later. Magnetism ...

The sun has a flair for putting on spectacular shows, and last month’s was a doozy. Images taken at various National Science Foundation-funded observatories caught our local star in the act of ...
