Magnetization identification problem - Illustration of an effective approach
This paper deals with the problem of magnetization identification. We consider a ferromagnetic, body placed in an inductor field. The goal of this work is, from static magnetic field measurements taken around the device, to obtain an accurate model of its magnetization. This inverse problem is usually X-posed and its solution is non-unique. It is then necessary to use mathematical regularization. However, we prefer to transform it to a better posed one by incorporating our physical knowledge of the problem. Our approach is tested on the magnetization's identification of a real ferromagnetic sheet.
