Why Use Multipole Magnets vs Single N/S in 6V 3W Bike Dynamo With 2cm Friction Wheel?

I'm hoping with both of us looking at the same thing.... will help. HERE's is the the curiosity. This magnet has x poles (more than just 1 N & S) BUT~ each poles is so small (in terms of *effective* area, as well then, in terms of *effective* power.... YES ? BUT~ a neo of the same (Dia 2.5cm) dimension with only 1 N & S arrangement has well in excess of ....... both of the above's *effectiveness* SO WHY, the 1st.... for its particular... function ? = 6volts/3watts with Dia-2cm friction wheel against a bike wheel, 26inch circumference. @ 15mph.

Here you are read this very intersting article about absolute zero and magentic changes of metals at -373 or absolute zero 0 kelvin

Magnet misbehaves near absolute zero

Feb 21, 2007

The strange behaviour of a magnet near absolute zero temperature provides the first direct evidence that some quantum phase transitions proceed very differently than the conventional phase transitions that occur at higher temperatures. Researchers in Germany applied a magnetic field to a metallic compound and watched it transform from a magnet to a non-magnet -- just as expected. The surprise came at higher field strengths, where a puzzling change in the character of the metal was observed. As the temperature was lowered both the magnetic phase transition and the mysterious change converged on the same magnetic field value -- the "quantum critical point" -- defying the conventional method of characterizing phase transitions in terms of a single "universality class" (Science 315 969).

Curious !
Hello Mark,
No I didn't know all that ( knew that some sort of *SOMEONEs*... was/is doing some very strange things though)
BUT~ Tell me ~ Is your response telling me you are or are not either an Engineer or Electrician or both.. or that you would rather.... i ignored both the questions and the reasons... i ask them ?

No me according to my dearest friends I am but a nothing so there you go such is life I guess I ma content with this comments knowing that being a nothing has its wonderful attributes

As they cant blame you when it goes wrong because you did try to tell them and give good advice at the time

So I am quite content with that thought and will bear that in mind if they ever need advice or help or anything done for them because they will know the answer before they even ask me

Easy isn’t it ( I have a memory like an elephant I don’t forget )

Well People,

It seems I have a Talent for upsetting people. Oh~ I've known about it for a very long time indeed, BUT~ still surprises the hell out of me !
FOR I KNOW...... THAT THAT..... IS NOT MY INTENTION !

What hurts though.... is that all i ever get... is an Alert and rub out of whatever it is I've done wrong, if as here so lucky, BUT~ normally... just a close down of the thread or registration.
NO~ who, how, what, where... nothing!
AND~ the really hard part.... is I'm not allowed to feel insulted.... by that .

AND YES~ I do know that the result of me posting the above may mean the end of me here.
