This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

A new vortex electric field with the potential to enhance future electronic, magnetic and optical devices has been observed by researchers. A new vortex electric field with the potential to enhance ...

Researchers in China have shown that applying strain to a composite material using an electric field induces a large and reversible caloric effect. This novel way of enhancing the caloric effect ...

Magnetic sectors were the mass analyzers used in the early days of mass spectrometry. Those instruments were quite large, and today, other, more compact, types of mass analyzers capable of separating ...

An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives ...

Like a shaggy dog in springtime, some black holes have to shed. New computer simulations reveal how black holes might discard their magnetic fields. Unlike dogs with their varied fur coats, isolated ...
