Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...

Friction usually announces itself through contact. A chair scraping across a floor, a tire gripping asphalt, a hand sliding ...

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.

The new miniaturized structure requires a few thousand times less power than larger magnets and it could help bring ...

New method detects magnetic signals in metal that make it possible to predict fractures before they occur and prevent critical failures.
