Abstract

Compound magnetic materials based on parallel continuous ferromagnetic micro-wires embedded in a body made of polymeric material can potentially offer significant mechanical advantages over well-known fragile ferrite in some applications where the magnetic material has to withstand mechanical vibrations. Since the diameter of the magnetic micro-wires is very small (10’s of um) compared to the rest of the dimensions (100’s mm to 10’s cm), and the number of micro-wires is in the order of 1000’s, brute force simulation by Finite Element Method is not possible. In this work, a method to overcome this limitation is proposed based on the use of a homogenous material that will behave, in a macroscopic sense, as the compound magnetic material. The physical properties of the homogeneous material are obtained in different directions, due to the inherent anisotropy of the compound magnetic component, by means of analytical equations.
