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.

When load increases steadily, so does friction, but in the realm of magnetization dynamics, things aren’t so simple.

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

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 is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic ...

Friction is an everyday phenomenon; it allows drivers to stop their cars by breaking and dancers to execute complicated moves on various floor surfaces. It can, however, also be an unwanted effect ...

CAMBRIDGE, England, July 22 (UPI) --Scribbled pages in a notebook of Leonardo da Vinci, previously dismissed as nonsense, have been revealed as the polymath's earliest musings on the laws of friction.
