The article deals with an analysis of magnetic fields of electric machines and electromagnetic devices on the basis of their circuit mathematical models. The magnetic systems of electrical devices in these models are presented in the form of planar nonlinear magnetic circuits with lumped elements. The parameters of these elements are determined on the basis of geometric dimensions taking into account the design features of the devices and the physical parameters of the environment.

The structures of the frequency-guided calibrator, measuring transducer and DC comparator based on quantum magnetometric sensors are proposed. The peculiarity of the proposed complex is the use of the universal structure of the QMS, for which only external commutations determine the type of device and its purpose.
