Demagnetizing Factors of Ferromagnetic Bars upon Magnet Saturation
Source abstract
Abstract
Peculiarities of magnetization of ferromagnetic bars in a magnet-saturation regime are considered. By an example of a model specimen made of an isotropic ferromagnet in the form of infinitely long bar having a rectangular section and magnetized in a transverse magnetic field, calculations of magnetic parameters for a central section of the body are performed. It is shown that, as the magnet saturates, the central demagnetizing factor of ferromagnetic bars of any relative length always exceeds the demagnetizing factor of a uniformly magnetized bar because of the “ rotational” magnetization of the material.
