Permeability in down draft sintering process in steelmaking processes is well known not to be good because load of sinter cake oppress permeability in the lower layer of sintering bed. If the sinter cake as paramagnetic material could be suspended by magnetic force, it is expected that permeability will be improved. This paper presents theoretical and experimental characteristics of three magnets, i.e. electromagnet using permanent magnets, electromagnet using a high Tc superconductor as a permanent magnet and superconducting magnet in order to develop electromagnets for magnetic suspension of the sinter cake. The following results were obtained.<br>(1) It was verified that the sinter cake as paramagnetic material having relative permeability of 1.2 _??_1.8 could be suspended by the magnetic force, <br>(2) Calculated values to the magnetic flux density and the electromagnetic force were agreed with measured values within the error of ±10%.<br>(3) As a result of comparison to above three electromagnets, it was clarified that performance of supercondcting magnet is better than those of other electromagnets considering form saving energy and magnetic force.
