@sonhouse saidFirst it is atomic magnet and now magnetic moment again. Why are you using two different terms for the same thing? Are you going to say wave function next?
@Metal-Brain
EVERY atom from the top of the periodic table to the bottom has magnetic moment, some more than others but they ALL have some magnetic field.
@humy saidI meant atomic more in the sense of indivisibility rather than an atom as such. I was imagining the idealised case of a current loop of arbitrarily small radius.
Just look up 'atomic' in the common English dictionary and it world say/imply "adjective
"relating to an atom or atoms."
"the nature of matter at the atomic level"
Chemistry
"(of a substance) consisting of uncombined atoms rather than molecules."
Therefore "atomic magnet" means an atom that is acting like a magnet.
The thing is, that was just pl ...[text shortened]... osed to a technical term.
So if you cannot even understand that then you will never understand it.

You have digressed away from spin to magnets. Perhaps you should try explaining magnetism is my other thread since you cannot stay away from it here.
Does electron spin cause magnetism or does magnetism cause electron spin? You cannot have it both ways.
@metal-brain saidThis is like the old question about whether a tree falling down in the woods makes any sound. We have theories about things outside our direct sensory experience, which are based on our experience of the world. We know that angular momentum is conserved. When a metal rod is placed in a magnetic field it starts to rotate, this is called the Einstein-de Haas effect [1]. Because the magnetic moments of the electrons line up with the external field and the magnetic moment vector has the same direction as the spin vector the total angular momentum of the iron bar changes and there is a measurable torque. This demonstrates the connection between intrinsic spin and angular momentum.

@deepthought saidSo what you're saying is that Einstein is a hare??????

@deepthought saidThis is NOT like the old question about whether a tree falling down in the woods makes any sound. Stop making silly comparisons in a vain effort to digress and avoid answering valid questions.

You digressed so much into multiple jargon terms you have reversed your cause and effect. Explain yourself.
Does electron spin cause magnetism or does magnetism cause electron spin? You cannot have it both ways. FAIL!
@sonhouse saidDoes electron spin cause magnetism or does magnetism cause electron spin?
@Metal-Brain
That's rich. Telling a Phd physicist fail? Where is your Phd to back that up?
He cannot have it both ways. It doesn't take a genius to figure that out. He went from one cause and effect to the opposite. He digressed into failure. That is evident.
@sonhouse said"De Haas" means "the Hare."
@KazetNagorra
Hare hare, why do you say that?
I was just mocking MetalBrain's non sequitur-style questions.
@metal-brain saidYour post contained several questions I answered the first one about how we know it's spinning. As far as which causes which the chain of explanation is from charge and spin to the presence of a magnetic moment.

@deepthought saidI asked what was spinning, not just how we know "it" is spinning. You have not even told me what "it" is.

Does spin cause magnetism or does magnetism cause spin? Which is it?
