The ponderomotive method of obtaining information on the magnetic susceptibility of ferroparticles of different media, including the production of glass and ceramic, is examined. Acharacterization is given of the corresponding magnetometer with spherical pole pieces making it possible to create and identify the required (for locating the studied samples) stability zone of the induction gradient—in the vicinity of the extremum (characteristic for such poles) in the coordinate dependence of the gradient. Examples are given of the identification of the coordinates and sizes of such zones, specifically, with up to 3% departure from the average value of the gradient.
