Eddy Current Field in Uniform Medium Produced by a Coil

摘要: 以半无限大平板导体为例，直接从麦克斯韦方程推导出涡流电流密度计算的积分公式。用MATLAB软件编程计算了空心线圈激发的涡流分布情况，为检测系统的参数设置提供了依据。结果显示，在一定的条件下，即使在构件内部数十倍的集肤深度，仍然有很强的涡流分布。

Abstract: Taking the example of a half-infinite conducting plane, a formula for computing eddy current density is derived directly from Maxwells equation. By use of MATLAB, computing a distributing of eddy current which is inspired by a coil, that can be used as the parameter setup foundation. The results show that in depth of ten skin depth, the eddy current density is still high.
