The paper presents the relative magnetic permeability and the calculation model of porous metal foams. First, the porosity of porous foam metal is tested and obtained by the fusible paraffin; the magnetic permeability of three kinds of porous metal foam, that is, Fe, Cu, Ni, with the same structure parameters and different relative permeability are tested by vibrating sample magnetometer (VSM). Based on the equivalent reluctivity, the initial relative permeability of the electrodeposited metals is simulated and the calculated results are close to the testing results. The results show that the calculation model can be used to describe the relative permeability of electrodeposited metals, at the same time, according to the calculation, the relative permeability of porous metal foams will increase with the increased relative permeability of electrodeposited metals, and decrease with the increased porosity, which provide the theorical and experimental proof for the research on magnetic characteristics of porous metal foams.
