Abstract

The paper presents a solution for the case of a ferromagnetic ball placed in a homogeneous ac field. The studied characteristic is the frequency dependence of the magnetic permeability derived from experimental data with the help of the previously developed technique for determination of the magnetic permeability of samples in ac fields. Hodographs of the signals from the pickup coil and the effective magnetic permeability are given.
