SOME ASPECT OF MAGNETIZATION PROPERTIES OF THE GRANULAR BEDS

Magnetization properties of the packed beds that are constructed from the ferromagnetic balls and metal chips have been examined. The average magnetic permeability and magnetization curves of the nonhomogeneous ferromagnetic granulated medium (different size polyballs and chips) have been determined by using the “channel-by-channel magnetization model”. From the magnetic properties of the single chain of the different sized balls as an element of the chain bundle in the polyball medium, application conditions of the model to the polyball medium was estimated. New correlation’s for the influence of the packing density factor or the bed porosity change on the average magnetization curve has been evaluated. A new correlation between the packing density factor and the size of the beds element and also a relationship of relative magnetic permeability of the beds elements-external magnetic field intensity were obtained
