The different colors indicate how high in the sky the electrons collide with molecules in our atmosphere. Red Auroras, like the ones we've seen recently in Arizona, occur above 200 kilometers. Green ...
A DC motor (direct current motor) is a rotating machine which receives direct current and transforms it to mechanical energy most typically in the rotational form. It operates through the application ...
NV center quantum sensors provide high-precision, nanoscale measurements in condensed matter, linking physical properties to inaccessible correlation functions.
Melexis has announced a magnetism-based current sensor that needs no ferromagnetic core, for measuring currents through power PCBs and busbars (see ...
