An innovative method is introduced, designed for measurement of the magnetic susceptibility of weakly magnetic materials. The method uses magnetic resonance (MR) tomography and it is necessary to immerse specimen into reference medium with measurable MR signal (water is suitable). Compared to the existing MR methods of susceptibility measurement, described method enables to determine the magnetic susceptibility of such materials which give no MR signal, but is suitable only for homogeneous materials with a regular shape. The principle of this method was analytically designed and numerically modeled.

Je popsána modifikovaná metoda měření magnetické susceptibility. Využívá MRI a je nezbytné umístit měřený vzorek do referenčního média vytvářejícího MR signál. Princip metody byl ověřen numerickou simulací.
