The conditions under which the result of a measurement of the magnetic permeability of samples in an open magnetic circuit can be used to obtain a reliable result of a calculation of the initial magnetic permeability μin and the maximum magnetic permeability μmax of structural steel are established. A formula is derived for determining the error of the calculation, taking the measurement error into account. The possible reason for the overestimated results of a measurement of μin of low-carbon and medium-carbon steels at high annealing temperatures is analyzed.
