Abstract :
In this research a perturbation model was developed to predict near fields in the presence of and within a ferromagnetic material. This was done by modeling the electric and magnetic fields of an infinitesimal dipole antenna enclosed by the spherical shell of a ferromagnetic material by an iterative technique given only the complex amplitude of the magnetic field in the near field as known
