ABSTRACT
The experimental methods for determination of the average, i.e. scalar, magnetic susceptibilities can be divided into three groups. In the first group there are methods based on measuring the force with which the sample interacts with a magnetic field. The second group is composed of induction methods. Methods based on the analysis of 1H chemical shifts in Nuclear magnetic resonance form the third group. The Quincke and viscosimeter capillary methods are designed for the studies of pure liquids, solutions, or gases. The more sensitive viscometer method was used for precise measurements of the magnetic susceptibility of liquids. The system of the Faraday methods can be used for study of the magnetic susceptibilities of solid samples, single crystals, and pressed pellets. The Faraday methods are more suitable for relative measurements. This is related to the big practical difficulties connected to measuring the field gradients.
