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.

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

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
