Abstract
This paper
investigates the magnetic properties of metal foams experimentally. A set of test rig, including the coils, the
magnetic core, is developed. The effects of metal foams with different materials and thickness on the magnetic field are
studied. The results show that, as for the same thickness of metal foams, if the relative magnetic permeability of materials is
bigger, the magnetic density flux in the gap will be bigger; to the metal foams with the magnetic permeability, the difference of
thickness will have effect on the magnetic field, and with the increasing of relative magnetic permeability, the effect of
thickness will be more obvious, which provide the experimental data for the research on magnetic characteristics of metal
foams..
