ing antiparticle, that is, the antiproton, antineutron, and positron, respectively. Antiparticles have the same mass and spin as their respective particles, but they have opposite values of such electromagnetic properties as charge and magnetic moment. Mass Driver - A device also know as a rail gun. Using a series of super electromagnets, a piece of metal is accelerated to incredible speeds. Electromagnetic Pulse - Otherwise known as an EMP. An EMP is a pulse of magnetic energy that is released as a side effect of a nuclear detonation. It will destroy the circuitry of any electronic device that is turned on when the pulse hits. ...
