Based on the analytical model of the magnetized parallelepiped magnetic field, a model of the pillar magnetic field was created. Comparison of the model with the magnetic survey at the Kurchatov station variational pavilion made it possible to determine the pillar magnetic susceptibility. The anomalous field distribution of the pit near the Paratunka observatory was studied. It was shown that the field distribution is consistent with the two-layer soil magnetic properties model with a magnetic susceptibility of 0.0066 for the upper layer with a thickness of 70 cm and 0.0087 for the lower layer. Models of the magnetic field distribution at the dIdD and POS-4 pavilions at Paratunka geophysical observatory have been created. The anomalous field amplitude in the dIdD pavilion can reach 30 nT at the height of 40 cm. Compensation of the pit magnetic moment and the base plate one in the POS-4 pavilion leads to a relative uniformity of the model field, which is – not more than 0.5 nT at the magnetometer installation height.
