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 ...

An electric field transforms an iron oxide nanoparticle suspension into a model for the emergence of complex dissipative structures. Researchers at Aalto University have shown that a nanoparticle ...

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 ...

Cuktech’s 10,000mAh magnetic power bank offers the best of both worlds: wireless charging and fast wired charging. Its lightweight design makes it easy to carry — and its tiny price tag makes it a ...

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 ...

By removing rare earths from the equation, these designs promise cleaner supply chains and more sustainable production.

(Reuters Health) - Electromagnetic fields produced by motors in electric cars don’t appear strong enough to interfere with implanted heart devices like pacemakers and defibrillators, a small German ...
