摘要：

The predefined spatial distribution and strength characteristics (absolute value and gradient) of a magnetic field are shown to be reproducible with the use of local sources of the magnetic field (permanent magnets). Consideration of the problem's symmetry allows derivation of some characteristics of the field in an analytic form without conducting numerical calculations.
