A railgun is a gadget that speeds a conductive shot utilizing to a great degree high current and electromagnetism. No dangerous powder required. Just batteries.The recently fabricated railgun is field tried at 20,500 joules. It is the main portable, shoulder mounted railgun. A railgun utilizes current to produce amazing attractive fields that move a conductive shot to high speeds (iron is a poor conductor and in this manner unsatisfactory). Aluminum has been the all inclusive shot decision for its low liquefying point, high breaking point, low mass, and high conductance. Too much hi tec talk for you here, just watch the video for yourself!
