THE CHANGE IN THE COMPONENTS OF THE COMPLEX MAGNETIC PERMEABILITY OF NONUNIFORMLY MAGNETIZED FERROMAGNETIC RODS

摘要

The results of experimental investigations of demagnetizing and surface effects in extended ferromagnetic rods, magnetized by the alternating magnetic field of coils of different length in the 20 Hz ― 50 kHz frequency band are presented. A physically justified explanation of the fact that the components of the complex magnetic permeability are independent of the length of the coil at the higher frequencies of this band is given.
