Abstract :
The finite element method for the computation of eddy current fields is presented. The method is described for geometries with a one-component eddy current field. The use of the method for the calculation of the impedance of eddy current sensors in the vicinity of defects is shown. An example is given of the method applied to a C-magnet-type sensor positioned over a crack in a plane-conducting material.
