A rigorous solution for the calculation of the magneticfield problem
Abstract
A method is presented for the calculation of the magneticfield strength inside as well as outside an inhomogeneously magnetized threedimensional body. Employing the method derived in earlier papers for the solution of the magnetic field problem of twodimensional magnetized body it is shown how the analytic supplement can be generalized for the threedimensional case. The calculation scheme developed here is well suited to the solution of the inverse magneticfield problem where the magnetization and/or the geometry is calculated from the measured magnetic field. With the help of the proposed calculation method a technique is described for the analytic continuation of the outer magnetic field into the inner region of a threedimensional magnetized body. Several examples explain the applicability of the method.
