摘要：

Many recent studies have made it possible to determine the demagnetizing factors of the magnetic materials of various shapes. However, since the actual internal demagnetizing factors are distributed differently in the non ellipsoid, there is inevitably an error with the actual value. Especially, the study for hollow cylinder that usually used demagnetization research for submarine is insufficient. Therefore, in this study, the distribution of the internal demagnetizing factors of the shapes was analyzed and compared with the results of the previous research. Also, new calculation method was proposed to determine the value of hollow cylinder model and verified with finite element method.
