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

Wear has major impacts on everything from the bearing of a wind power plant to an artificial hip joint. However, the exact cause of wear is still unclear. Scientists now show that the effect occurs at ...

This podcast series is all about forces. In this episode, James Stewart and Ellie Hurer explore scalar and vector quantities as well as contact and non-contact forces. They discuss the differences and ...
