With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

Abstract: Hall based current sensors are widely used in AC and DC high current sensing. Current in busbar generates magnetic field which is directed to hall sensor using a surrounding magnetic core.

The Component Abuse Challenge is dragging all sorts of old, half-forgotten hacks out of the woodwork, but this has got to be the most vintage: [KenS] started using a transformer as a variable ...
