The article presents a method for achieving a linear distribution of working magnetic fluxes along the magnetic circuit in ordinary and special structures with distributed parameters and nonlinear magnetic coupling. This is achieved by selecting an appropriate law of variation for the linear density of turns of a distributed excitation winding placed on long ferromagnetic conductors. Introducing the condition that the second derivative of the magnetic flux along the length of the circuit is equal to zero into the system of differential equations makes it possible to obtain an exact analytical solution to the nonlinear differential equations of these circuits. In magnetic circuits of ordinary structure, this law and the variation of magnetomotive force take the form of a semi-parabolic function, whose minimum value corresponds to one end of the circuit and maximum to the other. In circuits of special structure, this law becomes a parabolic function, whose minimum is located at the midpoint of the distributed-parameter circuit, while maximum values correspond to its edges. In both ordinary and special structures, the magnetic fluxes in long ferromagnetic cores remain strictly linear even for different values of the coefficient describing the nonlinear behavior of the circuit. The magnetomotive force between long ferromagnetic cores remains constant along the entire length of the circuit. Such circuit structures are highly effective for use in electromagnetic measuring transducers where a linear distribution of magnetic flux along the ferromagnetic conductors and a constant magnetic tension (magnetic induction) in the working air gaps are required.
