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 ...

Eddy current testing is a well-established method of nondestructive testing that is used to examine nonferrous/nonmagnetic materials such as condenser and heat exchanger tubes in power generation ...
