Abstract
The paper examines the chain of balls of densely packed granular medium (with mutually contacting granules) as a specific "elementary" magnet, responsible for the magnetization of the granular medium. Using this example it is shown that traditional "finite" problem of volume averaging of the magnetic properties of two-component ferromagnetic medium can be extended with specific values of magnetic permeability of elementary effective channel of magnetization. These values may be not only average, but also profiled. The authors obtained demagnetizing factor data of the granular samples on the basis of characteristics of average permeability. The relevant processing of demagnetizing factor allowed to find the general expression for its location. It is shown that the relevant data of various magnetization channel cores and samples of polyspherical medium correlates accurately.
