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, ...

Goudsmit Magnetics, based in Waalre in the Netherlands, has launched a rotating Cleanflow magnetic separator that can be cleaned without stopping production. It is compatible with free-fall lines in a ...
