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 ...
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 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 ...
