Magnets produce an invisible force that can push or pull objects without even touching them. This video explains how magnetic fields are formed, how poles work, and why magnets attract or repel. Learn ...

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, ...
