A Theoretical Investigation on Effective Permeability of New Magnetic Composite Materials

Magnetic composite materials play an important role in broad applications, such as transformers and electrical motors. In this research, it has been predicted the effective permeability of new magnetic composite materials based on Maxwell-Garnett models to specify effects of embedded inclusions. Therefore, it has been investigated on applied formulating new magnetic composite industrial materials by adding various types and percentages of particles (Fe, Silicon steels, Metglas, Co-Fe, Ni-Fe, MgZn_Ferrite, NiZn_Ferrite). All results have been investigated on the significant effect of inclusions distribution, inclusion types and their concentration on the effective permeability of magnetic composite materials; thus it has been controlled and enhanced the characteristics of magnetic industrial materials by using the particles structure of a random distribution of magnetic easy axes of the grains.
