Особливості збудження електромагнітних сил при магнітно-імпульсній обробці листових феромагнетиків

Abstract

The article subject is being related to the magnetic pulse metal forming some problem. The physical mechanism of the pulse magnetic fields force action on the thin-walled sheet ferromagnetic conducting plates is theoretically formulated and justified. It is shown the attracting forces what are caused by magnetic properties of the metals worked out are prevailing for the low working frequencies. In increasing frequencies over some fixed limit value the attraction is changed into repulsion what is caused by prevailing action of the Lorenz’s forces the nature of which is the electrical dynamical interacting the external fields with induced whirlwind currents.
