Youre wrong you know.. A rail gun DOES need magnets otherwise the lorentz force will not exist. It needs the magetcs to surround the rails perpendicular to them but along the same axis. The magnetic field in the projectile pushes against the magnetic field of the magnet.
A good question, tho, is could you build a magnetic gun using a magnetic projectile and a massively powerful electromagnet at the end. Then use a burst of magnetism to send the smaller magnet flying. Just a thought. ^^
