*The paper considers one of the variants of a constructive problem’s solution and the mathematical model design of the induction hardening process of the spherical surface. The induction heat treatment process is used for items of various and quite often of very complicated shape. One of the main objectives of the inductors design is to increase, as much as possible, the effectiveness of induction process, and decrease the inductor energy consumption. The main technological requirement in the operation of induction hardening is to ensure uniformity of the temperature distribution on the surface of the workpiece. An important aspect in the inductor design process is the choice of the conductor’s form and the air gap between the inductor and the surface of the heated product A software package Flux has been used to solve the problem of the induction hardening, designed for multi parametric of electromagnetic and thermal analysis. As a result, the magnetic field distribution, as well as the temperature distribution within the workpiece has been obtained.*
