ABSTRACT:
An electromagnetic railgun. The device features two electrically connected parallel rails. One end of each rail may be connected to a D.C. voltage source. At least one of the rails has a hole for closely receiving a metallic projectile. When the projectile is within the hole and the voltage is applied, currents flow through the two rails. Interaction of the currents with the self generated magnetic field causes a repulsive force between the two rails and launches the projectile outward from the rails.
