Abstract :
In this paper we analyze a three-dimensional method for the computation of the magnetic fields, produced by thin ferromagnetic shells. Integrodifferential equation is used to define the scalar potential distribution inside the magnetized region. Magnetic field inside a thin shell is calculated using FEM. This method is shown to give accurate results for the field inside thin spherical shells in the wide range of the shielding factor
