<p>In the experiment with creating an axial magnetic field in the liner of a shaped charge, a reduction in the penetration effect of the charge was recorded before its detonation due to the breakup of the shaped-charge jet by electromagnetic forces resulting from the sharp amplification of the field upon the collapse of the liner. The possibility is analyzed of attaining the inverse effect consisting in the penetration effect of a shaped charge due to the selection of magnetic-field parameters so as to avoid the breakup of the shaped-charge jet, preserving in this case the additional heating of its material by eddy inductive currents and its thermal softening whose consequence may be the increase in the jet′s limiting elongation. To achieve the objective posed, the authors consider an additional impact, on the jet, of a magnetic field created in the path of its motion. The research is based on numerical solution of a quasi-two-dimensional problem on the stretching of a cylindrical rod from conductive compressible elastoplastic material in the longitudinal magnetic field.</p>
