.... The coupled 3D magneto-thermal problem is formulated using the sub-domain method, image theory and the equivalent thermal network. Design/methodology/approach The 3D magneto-thermal problem is solved through a nonlinear coupling between an electromagnetic analytical model and a transient thermal analysis...

..., the magnetization distribution is obtained by expanding it into a double Fourier series along x- and y-directions (Figure 3) as follows: Induction heating Eddy currents Permanent magnets Three-dimensional Extremity effects Method of images Linear motion Induction heating...
