【Abstract】 A short review of the magnetic field characteristics of magnetized ferromagneticwires used in the high gradient magnetic separator and of the existing problems is given.Based on the similarity principle,magnetic simulation is used to the systematicstudy on the magnetic field of magnetized ferromagnetic wires.The study includes:the effect of the material and the form of the cross sectionand dimension of the ferromagnetic wire on the magnetic force of the magnetized field,and,the field distribution of array of wires.By means of mathematic treatment and calculation parameters of ferromagneticwire with round and oblong cross section are optimized.These parameters can be ofuse in ore testings and in practice.Results derived from theoretical consideration are confirmed by experiment onore separation.更多还原
