The presence of various systems for holding the test object in the area of experiments in the wind tunnel distorts the experiment results. One way to solve this problem is to replace the fasteners with an electromagnetic suspension. However, its design requires taking into account many different factors.

The aim of the article is to consider the key points in the mathematical modeling of the designed electromagnetic suspension for aerodynamic research.

The presented mathematical formulas allow designing an electromagnetic suspension with the required characteristics.

It will be possible to eliminate elements that are not related to the test object from the zone of the aerodynamic experiment. This will lead to the absence of the need for mathematical processing of the results in order to eliminate the influence of model mounts in the wind tunnel. It will also allow various other experiments to be carried out, eliminating the influence of forces and moments from mounts and stands.
