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, ...

On-demand control of stable toroidal vortices lays groundwork for robust wireless data encoding. (Nanowerk News) Researchers have created an optical device that can generate both electric and magnetic ...

Wearable devices for continuous non-invasive monitoring of physiological signals are crucial for preventive care and management of chronic conditions. However, these devices are either sensitive to ...

Adjusting magnetization orienting and conformal assembling of high-coercivity micro-magnets at the microscale remains challenging, despite long-standing demand for space-resolved magnetic modulation ...

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 ...

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 ...
