Abstract
Determination of relative magnetic permeability of magnetic materials with permeameters implies measurement of longitudinal components of induction and field strength in a sample of the material to be tested. The magnetic field strength in the sample can be determined be measuring the field strength on its surface. The instruments in use (Hall sensors, measuring coils) allow one to measure field strength near the surface (and not on surface itself), which reduces the accuracy in determination of the relative magnetic permeability. To increase the measurement accuracy, it is proposed in this paper that the correction coefficients should be determined in the induction range of interest. These coefficients, which relate the field strength values near the surface to those on the surface, are obtained by numeric calculation of the field distribution in the sample and near its surface. 5 refs., 7 figs.
