Best output: fewer big or more small magnets?

[capthook]

Thanks for the replies!

So - as the larger magnets will cause larger drag - to keep the RPMs constant (with the same power input)- the air gap will have to be increased.  Doing this will result in about the same output as the smaller magnets with a smaller air gap.

With a device having a maximum attainable RPM's, once this level is reached, smaller magnets will - in effect - be like adding to the RPMs. With smaller magnets, will the greater frequency of the changing magnetic flux provide enough extra output to compensate for the smaller magnetic field proving to be superior to lower frequency, larger/stronger magnets?

ie: large mags 1+1=2 : small mags 1+1>2 (because of frequency)
(similar to ->  iron core 1+1=2 :  hollow/or amorphous core 1+1>2  (all variables considered))

or does 1+1=2 no matter what you do?  More amp turns in a coil = larger drag = slower rmps = larger power input needed = larger magnets = larger drag = larger air gap = .................. aaaaaaaaagh!!!!!!!!!!!!   

Thus: it doesn't matter what size, because all things considered - it will be the same in the end??
It seems tweaking here and there should matter!  With a fixed surface area to place magnets - it should figure magnet size would be a variable to optimize.....just like core size/material, wire size, amp turns etc. can be optimized.................
Or is magnet size just one variable that can't be 'cause 1+1=2 no matter?
