Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and ...
New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...
Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a permanent ...
