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 ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...

Schematic of two magnetic layers composed of permanent magnets. The magnets in the upper layer are free to rotate, while those in the lower layer are fixed. When the layers move relative to each other ...
