A solenoid is a long thin coil of wire. Depending on the application there may be several layers of windings to the solenoid.
To produce this coil of wire, you need a former of some kind, on to which you can wind the wire.
Here the plastic pipe is the former.
As simple as that!
this is a long bit os drain pipe. and i have wraped around 3 core wire.
will a car battery do? it don't work. if a put a magnet on top if just twitches when i put current throught the wire any ideas? :?

I just made an coilgun yesterday and its still asembeld on my desk.
Capacitors are the key!
I used four 10 000 uF 64 V.I got an iron rod flying at 30 km/h
I had to put some heavy stuff on the platform to keep it from sliding backwards and off the table.
The capacitatator are in a voltage dubler and are charged to around 100V i have an 0,2 Ohm coil so there is about 500 Amps of curent rushing trough the coil.I used 1 mm wire and it got a litle warm after fireing.
You can see a comented photo of what did in the "show us your workbench" topic
That's not much of a solenoid!, it won't generate much of a field at all.
You might notice that other people are using ball point pen sized tubes, LOT'S of coil windings, and 100V capacitors with discharge currents in the 100's of amps.
This is a far more realistic approach, by using a drainpipe and three core mains cable, you probably couldn't afford to buy the wire to make a decent coil?.
