http://en.wikipedia.org/wiki/Magnetic_dipole

oneowone · Answer

$$M = nm$$

So 
$$m = \frac{ M }{ n }$$

oneowone · Answer

M = ?
n = ?

Out of all that information what should  I use to figure out the magnetic moment?

experimentx · Answer

i suppose so.

oneowone · Answer

ok, how can I do that?

experimentx · Answer

the easiest one is http://en.wikipedia.org/wiki/Magnetic_moment#Magnetic_pole_definition

oneowone · Answer

which formula to use?

experimentx · Answer

I don't see exact formula to use http://en.wikipedia.org/wiki/Magnetic_moment#Two_kinds_of_magnetic_sources

oneowone · Answer

So I have to figure out he magnetic moment of ONE atom the multiply it buy the number of atoms that exist?

oneowone · Answer

in the magnet?

experimentx · Answer

tha't s complicated

experimentx · Answer

there should be easier one.

oneowone · Answer

lol yea, but can you guess at least the moment will eventually be?
$$10A.m ^{2}$$
$$100A.m ^{2}$$
$$1KA.m ^{2}$$
$$1MA.m ^{2}$$

:P?
Im guessing it will be a low value, do you think it will be a high/low value?

oneowone · Answer

Im trying to at least, figure out how the moment will be, give me an example of a moment of an dipole please or something.

oneowone · Answer

I watched the view already before,
$$\mu= md$$
Now, I need to figure out the pole strength.
And then calculate the separation between each pole.
