If your generator doesn’t work for some reason:
•[FONT="] [/FONT]Try changing the distance between individual magnets.
Make sure you have some non-symmetry there.
•[FONT="] [/FONT]Try changing the numbers of magnets per set.
Moreover, the disc diameter is probably not a highly crucial
component, but changing it will require finding the proper
spacing of magnets to work with the different circumference.
You could try tighter circumferences just by scribing a line on
your rotating disc as a reference point.
You should try to go with weaker magnets for this replication.
Stronger magnets will require better engineering to prevent
detachment of the rotor magnets.
You do not want to seek uniformly magnetized magnets for the
[FONT="]rotor magnet. *Remember, non-symmetry is a key here.[/FONT]
