Abstract : A method and apparatus for detonating an explosive in response to the detonation of a remote explosive without damaging any components positioned intermediate the two explosives. A permanent magnet having a coil of wire positioned thereabout is positioned adjacent to one of the explosives, and the output from the coil is connected to the detonator for the second explosive. When the first explosive is detonated, the permanent magnet is destroyed to thereby collapse the magnetic field traversing the coil. The collapse of the magnetic field generates a voltage which is initiating detonation of same. The preferred embodiment positions the coil and magnet adjacent to an electronic time fuze detonator and lead charge at the forward end of a cargo-carrying projectile, whereas the second explosive is positioned at the rear of the projectile for initiating ejection of a payload.
