This video explains what magnets are and how magnetic fields are generated through the alignment of atomic structures. Magnets influence electric currents, force interactions, and are used in many ...

Repeated impacts can create minerals that lock in magnetic signals long after the Moon’s global field has disappeared.

Atomic scale copper rich layers inside rare earth magnets suppress demagnetization, improving strength, stability, and efficiency in motors and generators. (Nanowerk News) Rare-earth magnets are ...

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.

Friction usually announces itself through contact. A chair scraping across a floor, a tire gripping asphalt, a hand sliding ...
