Frequency dependence of magnetic permeability of hollow cylindrical ferromagnetic pieces
Source abstract
Abstract
The frequency dependence of the magnetic permeability of hollow cylindrical samples has been studied. Experiments were conducted in an inhomogeneous ac magnetic field generated by a narrow cylindrical coil. The pickup coil axis was aligned with the driving coil and the sample, and the distance between the coils varied during the experiment. The experimental data were compared to calculations of the real and imaginary components of the complex magnetic permeability of samples. Experimentally determined hodographs are given, alongside frequency dependences of the magnetic permeability components obtained at different diameters, wall thicknesses, separations between the coils, and sample lengths.
