Abstract
A novel application of the zoom-in technique for 3-D electromagnetic field calculation to 3-D remote field eddy current effect computation is introduced. The technique is especially suitable for problems that are essentially two-dimensional but with some local 3-D character. Significant reduction of computer resources is achieved by using this technique, since only a small portion of the whole calculation region, basically the 'three-dimensional part' of the problem, is under consideration. Some data from the solution of the corresponding two-dimensional or axisymmetrical problem are used as the boundary condition of the 3-D problem in computation. The validity of the method has been verified by a comparison of its results with those from an axisymmetric problem.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
