Railgun Project: Trial and Error

So far I've come across three problems: bad rails, and a small power supply. The rails need to have low magnetic memory, meaning that they don't retain a magnetic field after exposure to one. My rails, though, retained a HUGE magnetic field, so they didn't work. The problem with the power supply is that it is too small. It doesn't provide enough Volts or Amps to shoot a projectile out if the barrel. Right now when it shoots, the projectile welds to the rails, which is NOT good for the power supply. I may have a solution on hand for the power supply, namely a large transformer, but I'm not sure what to do about the rails. I guess I'll have to see what comes up! Back to the lab!
