is derived from lenz 39 s law a law of physics discovered by the german scientist h f e lenz in 1834 lenz 39 s law states that the electromotive force emf induced in a conductor moving perpendicular to a magnetic field tends to oppose that motion thus in accordance with the present invention the molten jet forms a moving conductor in the magnetic field of the magnetic armor thus the magnetic field acts to slow and deflect the conducting molten jet of metal in the process of slowing the jet the jet is broken up and dispersed over a wide area reducing the penetration capability of the jet fig1 a illustrates an exemplary arrangement of layers of armor utilizing a magnetic layer to disperse a shaped charge in accordance with the present invention referring to fig1 a the armor comprises an outer cladding layer 104 having a hard surface 118 a magnetic layer 102 an inner cladding layer 106 and a shield layer 108 spaced from the inner cladding layer 106 by an expansion space 110 an rpg 104 contacts the outer cladding layer 104 and triggers the shaped charge explosive 112 the explosive then melts a metal core and propels the molten metal 114 forward to penetrate the armor the molten metal 114 penetrates the outer hard surface layer 104 and then encounters the magnetic field layer 102 upon encountering the magnetic field layer 102 the metal jet 114 is dispersed 116 the jet may still be concentrated enough to penetrate the inner cladding 106 but continues to expand 116 in the space between the.
