Measurements uncertainty evaluation of spatial harmonics of an external magnetic field

The article considers the methodology for estimating uncertainties in magnetic dipole moment measurements using point methods of spatial harmonic analysis. The influence of systematic and random errors on the accuracy of measurements is analyzed and an approach to their minimization is proposed. The developed uncertainty estimation model is based on multiple observations, statistical analysis, and the use of sensitivity coefficients. The results obtained allow to increase the accuracy and reproducibility of measurements, which is critically important for scientific research, industrial applications, and high-tech industries. The proposed methodology contributes to the harmonization of metrological standards governing measurements of spatial harmonics of external magnetic fields. The use of the approach allows it to be adapted to various technical objects and to ensure compliance with modern metrological requirements
