Questions about making a railgun
I am thinking of making a railgun for a school project dealing with magnetism. I basically know how to make one, but most tutorials say anywhere from 300V - 600V for the current. However, since this is going to be my first time doing something like this, I don't not want to risk electrocution without any prior experience.
The projectile will be a short nail, probably be around 3 centimeters long and 4 millimeters in diameter. I want the range to be around 10 meters or more and should be able to pierce a layer of cardboard. The starting force that will just be an ordinary rubber band. This is more of a demonstration for myself to see what I can accomplish, so range and fire power doesn't really matter.
So basically my question is, what is a viable voltage for the railgun, given my specifications above, that will not take me on a ride to the ER. If should it shock me, then so be it, I just don't want it to be lethal when I do make a mistake.
Again, I am a novice at stuff like this and don't know much, so take into account of that fact when getting irritated at my question.
Thanks in advance.
