The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes magnetic realignment. The discovery won’t let you off the hook when dragging ...

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, ...
