Analysis of Magnetization Properties of the Ferromagnetic Granular Beds
(Ieee-Inst Electrical Electronics Engineers Inc, 2016) Abbasov, Teymuraz; Herdem, Saadetdin
Magnetization properties of the packed beds that are constructed from ferromagnetic balls and metal chips have been examined. The average magnetic permeability and magnetization curves of the non-homogeneous ferromagnetic granulated medium (different size polyballs and chips) have been determined 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 were estimated. A new correlation 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 bed elements, and also a relationship between the relative magnetic permeability of the bed elements and the external magnetic field intensity were obtained. The obtained theoretical results were compared with statistical data and an agreement was observed.
