The new miniaturized structure requires a few thousand times less power than larger magnets and it could help bring ...

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.

A magnet small enough to fit in the palm of your hand can match the strength of some of the world’s most powerful magnets for the first time. But superconducting magnets that produce strong magnetic ...
