I'm trying to explain some physics principles to a general audience and have a few related questions:
1) What's the name of the principle that distinguishes between randomly arranged particles in an iron bar and those arranged so as to magnetize it? Is it 'coherence' or something else?
2) Is it the same principle (in a general sense, e.g. 'coherence') that produces phenomena like laser light, superconductivity, superfluidity, etc.? If not (or even if it is), are there other common examples of the same phenomena?
3) Is it correct to say that the particles/waves in these coherent systems "take on field properties"? If not, what's a better way to describe the macroscopic effects.
I'm not looking for long technical answers; brief general explanations will do (hopefully, that's possible for such phenomena).
Thanks.
