I have a multistage coil gun. and i was wondering how exactly do u connect the coils together. lol i thought u take wire from the first coil and use that to start the second coil.

I'm a bit confused here, but perhaps I'm missing something. The coils shouldn't be connected to each other at all, or else they'd all activate at once.

okay so each coil is connected to a their own circuit correct?

Right, and the timing is set to maximize the payload acceleration. I don't believe that it is commonly done in coil guns, but mag-lev railroads also alternate the polarity of the drive magnets so they attract the load as it enters their influence, and repel it as it exits.

edit: Note that in the latter case, the payload itself must be magnetized.
