SET OF LABORATORY STANDARDS OF HOMOGENEOUS MAGNETIC FIELDS AND A METHOD FOR AUTONOMOUS CALIBRATION THEREOF Russian patent published in 2021 - IPC G01R33/00 

FIELD: magnets.

SUBSTANCE: area of application: for creating weak, medium and strong homogeneous magnetic fields in small volumes. The substance of the invention consists in the fact that the set of laboratory standards of homogeneous magnetic fields consists of circular excitation coils for creating weak, medium and strong magnetic fields, and a common shell-type magnetic core, wherein the dielectric frames of the excitation coils are unified by the external dimensions and commensurate with the internal dimensions of the shell-type magnetic core, the shell-type magnetic core is composite and consists of a straight cylinder with parallel ends and two flat flanges set from sheet electrical steel and fastened by through rivets and spot welding along the perimeters, mounted by through screws to the cylinder, the upper flange is easily removable and serves for loading and unloading of samples subjected to magnetic processing, the lower flange is rigidly mounted and the current leads of the excitation coils and magnetic field sensor pass through said flange, the circular excitation coils in the dielectric frames are made from copper wire with a rectangular cross section or from copper tape by a known method for close laying of the turns.

EFFECT: provided possibility of creating magnetic fields of standard accuracy in small volumes in the order of fractions of a liter with guaranteed high homogeneity.
