In this paper, aiming at the finite element calculation characteristic of electromagnetic field, the posteriori error estimation of electromagnetic finite element analysis of eddy inspection system is researched deeply. On the basis of pointing out the limitation of Zienkiewicz-Zhu method applied to the posteriori error estimation of electromagnetic finite element, a new method of posteriori error estimation of electromagnetic finite element of eddy inspection system is presented. Based on this method, combining with the simple and practical finite element calculation method presented by James R. Stewart and Thomas J. R. Hughes, a new hp adaptive finite element strategy used for the electromagnetic finite element analysis of eddy inspection system is presented.
