Yes, wrap the coil pretty tight and wrap both wires together...both the trigger and power wire together.

The thumbnail picture below (click it) shows how to wrap the coil so that when you put + at the top and - at the bottom, you will get a NORTH field at the top of the coil. As long as the wire at the top is coming off the coil towards you from around the right side and the bottom wire is coming off the coil towards you from around the left side and you put + and - as shown, you will get a NORTH field at the top.

I like to start with the wires coming off the bottom of the coil poking off from the left side pointing at me. Then, I wrap upwards and down up and down up and down and I try to end at the very top...that is just to prevent confusion, you could of course end them both at the top and both at the bottom, but this makes it simple.

If you wind the coil like that you get the north field when a battery is attached to the coil. Then if you take a permanent magnet and put a fact towards the coil like this, it will repel if you are facing the north of the magnet to the coil. If you have south facing coil, it will suck to the coil when the coil is powered.

I hope this helps. Can you draw a diagram of exactly what you build and the components you used, size of wire and how many wraps, etc... did you wrap it like I described or did you wrap it backwards? You can make the whole thing work in reverse but if you are able to easily, I would unwind the coil and rewrap it properly like the diagram.

I didn't post that Bedini link for you to go figure it out yourself, I just did that to provide a link. This thread is intended for first time schoolgirl motor builders.
