Original Abstract

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. For a non-homogeneous material and/or irregular shape this method must be modified, as is discussed in conclusion of the paper. The principle of this method was analytically designed and numerically modeled. Usability of the method was experimentally verified in the laboratory. Measurable value of the magnetic susceptibility is of the order 10-7.

Keywords

Magnetic susceptibility, magnetic resonance, MR tomography, gradient echo sequence, finite element method.
