Abstract
This paper documents the research towards the development of a simple approach to model composite magnetic materials through Finite Elements Method analysis. The computational problems found in representing composite materials at microscopic level are solved through a homogenization technique based on energy balance. The technique was used to estimate the effective permeability of a material, and through a larger scale simulation, its shielding effectiveness against extremely low frequency magnetic fields. The results were then validated using an experimental setup.
