Magnetic Properties of Ferromagnetic Samples of Various Lengths, Approximation of the Demagnetizing Factor

摘要

Families of dependences of the parameters of magnetic induction, permeability, susceptibility, and magnetization for cylindrical steel samples on the field strength H and the ratio of their length to diameter L / D are obtained. It is shown that the dependences of these parameters on L / D reach self-similarity regions (thereby proving the correspondence to the magnetic properties of the material) at different H -dependent L / D values, in contrast to the existing opinion. It is also shown that the range of L / D samples used in practice is characterized by an exponential relationship between their demagnetizing factor and L / D .
