ASSEMBLY OF SUPERCONDUCTIVE COILS AND EQUIPMENT FOR GENERATION OF MAGNETIC FIELD Russian patent published in 2013 - IPC H01F6/06 

FIELD: electricity.

SUBSTANCE: assembly (100) of superconductive coils, in which multiple blocks (110) of coils made of a superconductive material, is arranged coaxially relative to one and the same direction, and comprising elements (121) of magnetic field control, made of ferrite, a powder metal core or powder of permendur, which have higher magnetic permeability compared to the superconductive material, and are located near to the coil blocks. Elements of magnetic field control have a shape of a ring with an axis coaxial relative to each axis of coil blocks. Internal circular elements arranged in diametrical direction on inner sides of magnetic field control elements, and external circular elements placed separately in diametrical direction on the external sides of magnetic field control elements are larger than the elements of magnetic field control in the axial direction.

EFFECT: reduced AC losses.
