How to connect 2 coils?

    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. :confused:

    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.
