Abstract

An instrumental complex for reproduction, maintenance and transfer of the magnetic induction unit in the range from 0.05 to 2 T has been developed and researched. Homogenous magnetic fields of different values are created in a multiband electrical magnet. A special system for stabilization of the magnetic field provides standard deviation of the measurement result up to 1/spl middot/10/sup -6/. The nuclear-resonant teslameter makes it possible to measure the reproduced value with nonexcluded systematic uncertainty of 3/spl middot/10/sup -6/.
