Abstract: Relations between effective magnetic permeability of body-centered cubic,face-centered cubic and simple cubic lattices of conducting spheres and ratio of magnetic permeability,frequency are studied.The result shows that effective magnetic permeability is a complex number,and face-centered cubic lattices has the biggest magnetic permeability among the three cubic lattices in the limit of critical volume fraction;in  other words,face centered cubic lattice is the most steady structure of the three cubic lattices.The conclusion of the numerical calculation is in good agreement with experimental results in refs. [10-12].

Key words: magnetorheological fluids, conducting spheres, effective magnetic permeability
