Distributions of forces in the inductors used in metal processing in the pulse magnetic field

The method of computing the distributions of the mechanical forces acting on the coils of the inductor heads, as used in metalworking in the pulse magnetic field, was described in the present paper. The distributions of forces acting in the mono-layer inductors of different dimensions were determined and compared with each other, using the original algorithm of numerical calculations, prepared in the C++ language. The results of computations were presented for the case, when the inductor coils conducting the surge electric current were not loaded with the current of the semi-finished product—the idle state—as well as for the case, when the inductors are subjected to the action of additional forces, caused by the rotary currents, induced in the wall of the tube, expanded or pressed by the inductor. Moreover, the results of computations regarding the distributions of forces and stresses acting on the coils of the multi-layer inductors were also presented.
