These combined phenomena of induction, eddy current generation, and opposition are the fundamental principles of proximity, inductive displacement, and eddy-current sensors. The primary differences ...

The Science of It: Eddy currentsHearst Television participates in various affiliate marketing programs, which means we may get paid commissions on editorially chosen products purchased through our ...

Traditional eddy current and eddy current array technology follow the same fundamental principle. When alternating current is introduced in a coil, a magnetic field is produced (in blue).

John Hansen, Managing Director/CEO of Ether NDE Ltd, talks to AZoM about Eddy Current Testing. What is an Eddy Current NDT? Eddy Current Testing is one of the many Non-destructive Testing (NDT) ...

Eddy currents induced in the cup by the spinning magnet create a torque that turns the needle against the force of a hairspring. Pretty simple — but how to put the instrument to work?

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

It’s a simple probe that uses magnetic or eddy current principles. By putting the probe against a printing blanket, it can tell you packing/blanket thickness within thousands of an inch. It ...

Eddy currents were discovered by Foucault in 1851, but the technology was not used for industrial applications until the 1930s. "It's very exciting to take a 165 year old principle and discover a ...
