Physicists Discover Magnetic Mechanism That Challenges a 300-Year-Old Law of Friction

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 at the University of Konstanz have identified a new type of sliding friction that occurs without any physical contact. Instead of surfaces rubbing together, the resistance to motion comes [...]
