Abstract

The invention is directed to a hollow or projectile charge with an explos material charge (6) and a lining (9) acted upon by the detonation of the explosive material and forming a spike or a projectile (16). In order to achieve the highest possible accelerations for the spike or projectile, the lining (9) is constructed as a part of the hollow space (10) with walls (4, 5) of a good electrically conducting material in which a primarily fed magnetic field (H) is enclosed and compressed by means of the detonation of the explosive material (6). The hollow space (10) is preferably formed by means of a coaxial system (3) of an inner conductor (4) and an outer conductor (5), which coaxial system is short-circuited at both sides, wherein the outer conductor is encased by explosive material (6). During the detonation of the explosive material, the outer conductor (5) is pressed against the inner conductor so that the hollow space (10) located between the outer and inner conductor is constantly reduced.
