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, ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. WASHINGTON — ...

Inductors control electric current by using magnetic fields to resist sudden changes. This video explains how a simple coil can manage current flow and stabilize circuits in many electronic devices. A ...
