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.

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

Add Yahoo as a preferred source to see more of our stories on Google. Even famous thinkers like Leonardo da Vinci were fascinated by the physics of friction. What researchers do know is that the ...

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

Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, ...
