Original experiments with the eddy-current array used a flexible printed circuit array with 64 coil pairs, each one 4 mm in diameter. The engineering prototype board expanded the size to 256 coil ...
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 ...
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 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 ...
