Elements of the theory of substantially non-uniform magnetic fields measurement by magnetomodulation sensors are given. Magneto-modulation sensors consist of two parts: source of constant magnetic field and measuring transducer. Calculation of sensor magnetic systems is based on K.M. Polivanov's theorem of reciprocity. The theorem of reciprocity is adapted for calculation of magneto-modulation sensor magnetic systems due to the use of scalar magnetic potential function and normal component of magnetization vector on modulator magnetic circuit surface. The method of magnetic field intensity calculation created by cores of the magneto-modulation sensor of rectangular and circular cross-section, based on the analytical solution of integrated equation is developed. The method of field magnetization vector calculation in ferromagnetic environment is offered. The aim of the article is the attempt to develop the elements of the theory of magneto-modulation measuring sensors considering parameters of magnetic field source.
Key words: magnetization, sensor, function of potential, theorem of reciprocity, integrated equation, numerical decision, core, coil.
