Universal method for the calculation of magnetic microelectronic components: the saturated ferromagnetic rectangular prism and the rectangular coil

The paper presents a mathematical model applicable both for calculation of the 3D magnetic field outside a rectangular coil and demagnetization and stray field of a rectangular saturated ferromagnetic prism. An infinite thin surface current with surface density j (A/cm) has been used to model the coil block. Different mathematical models for analysis of the magnetic microelectronic components are discussed. Results of the calculation are presented.
