Abstract

Calculated parameters of large-volume calibration specimens are presented. The specimens are made of a disperse ferromagnetic mixture with the magnetic susceptibility χc ≥ 1 400 SI units encased in a spherical shell made of a dielectric with the magnetic susceptibility χ m d ≪ 1. The normalized magnetic susceptibility is determined for the calibration specimens. Its limiting value, equal to χ c c = 1.99 SI units, is determined by their spherical form and the volume concentration C V = 0.9, which corresponds to the volume fraction of the ferromagnetic component in the disperse medium. Relative error δ in the measurement of the specimen's magnetic susceptibility does not exceed ±1%.
