Coil Gun Electromagnetic Launcher (EML) System with Multi-stage Electromagnetic Coils
Journal of Magnetics, 2013 An electromagnetic launcher (EML) system accelerates and launches a projectile by converting electric energy into kinetic energy. There are two types of EML systems under development: the rail gun and the coil gun. A railgun comprises a pair of parallel conducting rails, along which a sliding armature is accelerated by the electromagnetic effects of a ...
