Video description

This video shows a U.S. Navy demonstration of a railgun. A railgun is an electrically powered electromagnetic projectile launcher. It is made of a pair of parallel conducting rails, along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature, and then back along the other rail.
