The diameter of the tube and the size of the magnets will also
affect how much voltage you get out of the thing. Try to minimize
the air gap around the slug/magnets as much as possible. Use a
smaller diameter tube or a larger diameter slug/magnets.

If Radio Shack still existed, you could pick up a spool of “magnet wire”, thin
stuff with enamel insulation. 26 or even 32 AWG should be fine for lighting an
LED. Mount that cardboard tube on a lathe or drill and put a whole bunch of
turns on it.
Faraday’s law says voltage should be propor
An old motor or speaker will have a decent amount of enameled wire it it that
you can use. Scrape or melt the enamel off where you want it to conduct.
Use two LED’s in parallel with the anode opposite directions and you should get
alternating lights when you shake it.
I wouldn’t worry about
This site shows the coil they are using. Lots of turns of small gauge wire.
The gauge is not important but the number of turns is.

Good sleuthing.
Now I’m wondering how long it would take high school students to connect a
battery to the coil and build a gun to shoot neodymium magnets.
Next project: railgun.

One of my sons did that in college. Multiple coils with timing or sensor Ed
switching between them. Less than impressive.
