Reproduction of four base magnetic units in the unified standard of VNIIM

The described measurement standard is developed on the basis of modern magnetic measuring techniques to substitute three standards operated earlier at VNIIM. In the unified measuring system the standard reproduces four base units of magnetic quantities, as well as the ratios of these units to the ampere: magnetic flux density (MFD) - T, magnetic flux (MF) -Wb, magnetic moment - Am
²
and MFD gradient - T/m. It allows realizing modern calibration system for magnetic measuring and reproducing instruments.
