Controlling magnetism in a device is not easy; unusually large magnetic fields or lots of electricity are needed, which are bulky, slow, expensive and/or waste energy. But that looks soon to change, ...

Small battery devices need magnetic switches that use power and take up space. These switches detect magnets and help devices run longer.

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

A research team has developed the first switch that turns on and off a quantum behavior called the Berry phase. The discovery promises to provide new insight into the fundamentals of quantum theory ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...

Factory-programmable digital Hall-effect sensors developed by Melexis Technologies integrate EEPROM memory that enables configuration of magnetic switching thresholds (including hysteresis).

The switches are offered with dry contact, npn, and pnp outputs in 0.5, 1, and 3-A ratings, and may have up to three contacts in a single housing. Adjustable sensitivity allows switches to "see" ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.
