The theoretical foundations of measurement uncertainty evaluation magnetic moment of radio electronic means using point methods are considered. A sequence and
implementation of the uncertainty assessment procedure is proposed. A model equation based on the multipole description of the object’s magnetic field is obtained. An analysis of the equation is made. The uncertainty budget has been drawn up. Found standard and extended uncertainty. The results are in demand for control procedures and tests in the area of technical magnetism. The results contribute to the standardization of the quality assessment of magnetic measurements.
