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

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.

When load increases steadily, so does friction, but in the realm of magnetization dynamics, things aren’t so simple.

“The next wave requires us to know things like the laws of physics, friction, inertia“ The next wave requires us to understand things like the laws of physics, friction, inertia, and cause and effect.

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...
