Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical neodymium magnet to ...

Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction. When an ...

A nondestructive testing technology called eddy current array (ECA) is capable of driving numerous eddy current coils that are positioned next to one another in the same probe assembly. In the probe, ...

Scientists from the Higher School of Economics and the Landau Institute for Theoretical Physics of Russian Academy of Sciences have investigated how vortex flows penetrate the interior of a liquid.

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...

A magnet sliding down a copper ramp is slowed by magnetic fields from eddy currents induced in the tube. A magnet sliding down a Plexiglas ramp is unaffected. A magnet sliding down a brass ramp goes ...
