Eddy current NDT and deep flaws (TEAM Problem 27)
A coil is stationary over a sheet of aluminium that contains a screw hole. Inside of the screw hole, a flaw is to be detected by two Hall effect sensors. The sensors are used to measure the horizontal differential flux density.
The following is based on the Testing Electromagnetic Analysis Methods (TEAM) Problem #27: Eddy current NDT and deep flaws. The benchmark can be found on the International Compumag Society's website (
TEAM Problems).
