ELECTROMAGNETIC DEVICE FOR INHOMOGENEOUS MAGNETIC FIELD WITH A STABLE INHOMOGENEITY ZONE Russian patent published in 2023 - IPC G01R31/12 

FIELD: magnetic properties measurement.

SUBSTANCE: invention relates to magnetic properties measurement field. Electromagnetic device for inhomogeneous magnetic field with a stable inhomogeneity zone consists of a magnetizable magnetic circuit with opposite polar tips that are mutually remote from each other at a distance b and have end spherical surfaces of diameter D, when the inhomogeneous magnetic field between them defined by computational experiment and recorded by limiters is required for the stable inhomogeneity research zone and the stable inhomogeneity research zone, the practically stable inhomogeneity zone limiters, which are used for placing the object under study in the zone by means of the actuator, are palced on the surface of a non-ferromagnetic reflector located between the pole tips and light markers by means of beams emitted by light sources that may be programmed and moved depending on the b and D parameters being changed.
EFFECT: invention provides possibility to extend the device functionality and increase its efficiency in preparing for and conducting applied scientific researches.
