Let's estimate what kinds of conditions a "military grade" railgun would require. First of all, let's say the muzzle velocity has to be 1000 m/s (actually slow for a railgun). The magnetic field has to be big and so let's choose 10 T. For the gun length, let's choose L = 5 m. Suppose mass of the rod is 0.1 m and its length is 20 cm. The rod maintains contact as it slips. Ignore rolling. L a) Calculate the force that must be acting on the rod. b) To achieve this force, what current must be delivered to the rod?
