METHOD FOR CONTROLLING THE MAGNETIC SUSCEPTIBILITY OF A PARTICLE BY THE CONCENTRATION DEPENDENCE OF THE SUSCEPTIBILITY OF THEIR DISPERSED SAMPLES Russian patent published in 2022 - IPC G01N27/76 

FIELD: measuring technology.

SUBSTANCE: invention relates to the field of magnetic measurements. The method for monitoring the magnetic susceptibility of a magnetically active particle contains steps at which the magnetic susceptibility of ‹› specially prepared dispersed samples (liquid dispersion media subjected to solidification) is measured with a preliminary distribution of magnetically active particles over the entire volume of the sample with a certain value of the volume fraction of such particles. The dependence of ‹› on is obtained for the studied samples with the identification of the initial linear section of this dependence, within which the relationship necessary for controlling =‹›/ is valid.

EFFECT: reduction in time and simplification of the process of preparing dispersed samples, an increase in the efficiency and accuracy of monitoring the magnetic susceptibility of individual particles of these samples.
