The features of an “elementary” effective magnetization channel are studied for a chain of spheres as a specific magnet responsible for magnetization of the granular medium as a whole (based on a model differing from the models of traditional averaging of magnetic properties over the volume). Matching experimental and theoretical data on the permeability (radial permeability profile) of a magnet-channel (core of various radii and isolated tubular layers) are compared.
