How does a black hole generate a magnetic field and how can it be measured and visualized? Alan CroftSeattle, Washington As ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

Spacecraft reentry environments lead to high magnetic Reynolds numbers, resulting in complex dynamics for magnetic flow ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use to ...

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...
