ABSTRACT:
A method of analyzing and apparatus for analyzing materials comprising subjecting a sample of the material to a non-homogeneous magnetic field having a predetermined time-dependency with respect to the sample such that a localized volume of the sample is subjected to a field the time dependent variation of which is unique with respect to the remainder of the sample. The sample is irradiated with radio-frequency energy to cause gyromagnetic resonance in the sample, and electrical energy produced by gyromagnetic resonance in the localized volume is measured.
