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

Eddy currents are specialized electric fields that are generated in the presence of a magnetic field and are often seen as a secondary field. An Eddy current can be produced by both electromagnets and ...

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 ...

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 ...
