Do you know where the flux is most dense on ur magnets?

and have you tried clamping the flame in between two magnets?

if you get one of these
Link2
you will know where exactly the flux lines are, even tho you can't see them.

I have some magnetic viewing paper that shows the flux lines. Here it is Link2 Thanks. Btw, for those replicating this experiment, I recommend you purchase THESE exact magnets Link2 to reduce variables such as different manufacturers quality control issues, etc. Good luck, let us know your results!

Assuming that the effect is due to the magnetic field (or rather the derivative of the field, which is really what attracts or repels stuff), and not some other mysterious effect, I would say the bigger the magnet the better. The ones used by CM are only of strength N38, fairly weak compared to the N50 magnets also available. They are also not that big.

Still, in order to boost the magnetic field density by another order of magnitude or so, it would be useful to provide an iron flux return path. A CC transformer core would do the job, pole shoes would further increase the flux density. I am talking about a construction like this: Link2

fields exert influence on the shape of candle flames..."

Cold plasma is a gas. Mmm... just not as hot as an arc i guss?

Interestingly, the candle flame deflects most noticeably with these particular magnets Link2 compared to many other neos that I have, in different sizes and shapes, and some considerably larger. The other neos in my collection don't produce as noticeable of a deflection to the flame. I can't say exactly why, but it may support the idea that the geometry of the magnet plays a role. CM
