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 ...

Eddy current non-destructive testing (ECT) exploits electromagnetic induction to detect subsurface defects in conductive materials without requiring disassembly or contact. An alternating current in a ...

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 ...

During manufacture and assembly of products, there is a wide range of testing and inspection carried out to ensure the materials and items satisfy their specifications or are fit for the required ...
