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 ...

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 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 electrical currents induced within conductors by changing magnetic fields. They are commonly used in nondestructive evaluation (NDE) and corrosion monitoring of structures with ...

Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...

The description of an eddy current separator (ECS) sounds like the wrong answer to a science quiz: How can it use magnets to repel, rather than attract? And how can it affect nonmagnetic metals like ...
