Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

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.

They move through the Sun like slow, immense swells, far below anything telescopes can see. For years, those depths have ...

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 ...

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 ...

There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

Researchers at Chalmers University of Technology in Sweden published their findings in Advanced Materials, demonstrating a material that allows two competing magnetic forces to coexist within a single ...
