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.
It's part of the STEP — Spherical Tokamak for Energy Production — program implemented by U.K. Industrial Fusion Solutions.
People have warned for years that magnets can wipe out hard drives, but the real answer is a lot less dramatic than that old ...
Why rare-earth magnets are a big deal. These aren't just fridge magnets. MP Materials mines and refines so-called rare-earth ...
Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...
One untapped resource to meet the rising need for rare earth elements: recycling what's already been used.
How Does Superheating Reduce the Magnetism of Magnets? To understand how temperature might affect a magnet, you need to look at the atomic structure of the elements it is made of. Magnets are made of ...
