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.

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

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes ...

Hundreds of millions of years ago, Earth’s magnetic field behaved in a way that has long baffled scientists, showing wild and ...
