Abstract
An apparatus and method for the non-destructive determination of the content of the magnetizable and/or non-magnetizable portion of a sample, in which the sample is provided in an air gap of a magnetically conductive yoke, an alternating magnetic field is generated by an alternating magnetic field strength of an excitation coil in the yoke, and first measurement data relating to the sample are collected using a measuring device which is inductively coupled to the yoke, and comparing the first measurement data to second measurement data relating to a reference sample, wherein the same alternating magnetic field strength or the same alternating magnetic field is applied to both the reference sample and the sample and the difference between the two collected sets of measurement data is included as a measure in the determination of the content for the magnetizable and/or non-magnetizable content portion of the sample.
