In the article, a study of the topology of an axisymmetric magnetic system «Hal-Bach» type using a two-component threedimensional scanner of a magnetic field. Obtained information on the distribution of the normal component of the induction magnettion of the field became the basis for the calculations of the magnitude of attraction of the ferromagnetic sample-ring to the studied magnetic system. The work also measured the force of attraction of the magnetic system to the frame using the tensile machine. The calculations are in excellent agreement with in situ measurements of the force of gravity for zero clearance at which the sample is in direct contact with a magnetic system. The magnitude of the gap up to 10 mm, the misalignment of the estimated and measured values of the magnitude of the force reaches 27%.
