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

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 ...

Scientists for the Event Horizon Telescope collaboration say the magnetic structure of the Milky Way’s central Sagittarius A* black hole is “strikingly similar” to the bigger singularity in the middle ...

Conventional hard disks are based on ferromagnets—materials in which the magnetic dipoles, or spins, associated with each atom all point in the same direction. This alignment gives the material a net ...

Non-collinear antiferromagnetic materials, which have a net magnetic moment nearly zero, yet exhibit significant anomalous transverse transport properties, are considered as candidate materials for ...

Physicists at the New Jersey Institute of Technology have traced the Sun’s magnetic engine to a depth of roughly 200,000 ...
