The article presents a method for ensuring a linear distribution of working magnetic flux along a distributed-parameter, nonlinear magnetically coupled circuit of simple structure by selecting an appropriate law for varying the working air gap between ferromagnetic cores. It is shown that introducing the condition of zero second derivative of the magnetic flux along the chain length into the system of differential equations enables obtaining an exact analytical solution. It is established that the air gap variation law and the magnetic voltage distribution follow a semi-parabolic function, with minimum at one end of the chain and maximum at the other. It is also demonstrated that the magnetic flux remains strictly linear even for different values of the nonlinearity coefficient, while the magnetic voltage variation increases with its growth
