A new analysis of the 2018 collapse of Kilauea volcano's caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the conditions ...
Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...
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.

Challenging a 300-year-old law of friction
Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic ...
Say we consider a simple experiment of balancing a wooden rod on two fingers. The finger on the left, (1), will remain stationary, whereas the finger on the right, (2), will be moved toward the left.
