Calculation of electrical parameters for different schemes of ferromagnetic pipe

Problems of simulation of electromagnetic field taking into account hysteresis effect, at low-temperature heating of ferromagnetic steel, are considered in the present paper. Methods of numerical calculation of induction, resistive, and inductionresistive systems for ferromagnetic steel heating are developed. Comparison of electromagnetic field parameters in ferromagnetic steel for induction, resistive, and induction-resistive heating units is made, based on the methods obtained. The hysteresis effect contribution into the total heat output in the heated ferromagnetic material is estimated
