Hello, and welcome to Instructables!
I have realized that you did not receive a greeting from ewilhelm (Eric) or the Instructables Robot, so here you go!
I do NOT work for Instructables, but I give out greetings once in a while and help people on Instructables.

Welcome again, and just have fun here.

If you have any questions, you can contact the Instructables staff, or me. If you do not know who they are, you can check them out here. Just click on one of the accounts at the link I just gave you (somebody in the Instructables Team/ Interns/ Advisors) and ask them in a private message or comment. You can click here for a guided tour of Instructables, or click here for an Instructable about how to make your own Instructable.
You can ask me about anything on this website, how to change your profile avatar icon, posting Instructables, anything! I'll be here for you.

Have fun here at Instructables!

A simple version is made within two minutes. Take aluminum tin foil, cut two long strips that are 1-2" (2,5-5cm) wide, glue them to cardboard. Buy two strong disk earth magnets (neodym). Thats the really, really strong kind. Weaker will not work. If the magnets are goldplated thats even better. Attach the disks to a iron metal bolt. The sides attached must be repelling sides! Now put them like a wheel-axis on the aluminum (the aluminum should not have contact!) Attach a 9 volt battery pack to them. The "wheels" will roll! Now if you have more voltage and different setup, you could fire a projectile with it. A railgun usualy has more of a sliding-track instead of wheels, but is harder to build- and dangerous if you work with more voltage. Coilguns are also a popular project. A coil will pull in a nail if electricity runs through it. A series of coils will switch on and off to pull a nail forward, where it gets real fast.
wow you really got around for a one week member anyway how does a railgun work?
