Abstract: This paper reports about the validity of the numerical model for presuming the internal current of the superconductor that is difficult to measure. The validity of the numerical method is confirmed by the simple analysis model. This model is constituted applying boundary element method and the difficulty of measuring the internal current is solved by the inverse problem from the exterior flux density distribution. Since the application of this model draws the solution of an irreversible magnetization phenomenon not clarified, the apparatus that uses the superconductor will develop.
