The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Diamond detection A sensor based on NV centres has been used to measure electrical currents in the heart of a rat. (Courtesy: iStock/Gizmo) A diamond-based sensor that maps out the subtle electrical ...

Incredibly, for the first time, scientists have unraveled the mechanisms at play when rubbing a surface creates an electrical current, something that was first recorded in 600 BCE yet not fully ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...

The film explains the concept of electrons and their role in electric circuits. It describes how electric current is the flow of electric charges, primarily electrons, which cannot be seen but can be ...

A material cooled near absolute zero produced an electrical signal that physics said should not exist, revealing a new kind ...
