    I was wondering how to make, if at all possible, a field that would contain very fine magnetic particles in a suspended cloud.

    Sorry if this sounds stupid, I am not to great with magnetic fields and this may be a very simple problem that i just don't know how to do, but i cant seem to find my answer without asking specifically.

    you need to realize that when we get a magnetic field, its just because more atoms are pointing in one direction (facing up if you will)

    That really doesn't answer my question

    Ok first things first, if you have a very fine suspension of magnetic particles they will eventually form a single mass thus it would (seem) not possible using superconductors may provide a path to success. Google 'levitron' go and buy one, they are one of the greatest toys ever!

    The thing is, I want them to form a mass ball, I just want it to be a really hard to see ball. the intention is to mix magnetic dust in with some small transparent crystals and suspend it but have it be close to invisible as possible.

    I would like to use this thread to ask a sub question, that might help the thread starter.

    As I understand a electron exists because its moving and is not bound to x,y,z so when you talk about a magnetic field, you talk about an object that has two pols.

    But because of that the electron is moving around with the movment we call spin and that it is, in more places at the same time. I hope I got it right, now to the question.

    If the neagtiv side is souranded by electrons or the electrons are around the atom core, and souranding the south side of the object.

    I wonder what happens to the north side is it the same as above, but with protons?

    If that is the case, can the proton also be describe as a weave rather than a paricel?

    Or is it that the north side contains less negativ particels that it becomes posetiv?

    Back to the original question, then, I think you could if you had an alternating magnetic field, and more than one field, coming from different directions. Or, you could use sound. That's what I'm thinking... Very high frequency sound in a standing wave, from 3 directions, like this: http://www.youtube.com/watch?v=S4exO4CuoSU "Ultrasonic Levitation" Yes, that would work nicely. But you do need very high frequency, so the dust particles are closer together.

    That is very impressive but I don't know how stable that would be for not throwing the small crystals I want to suspend out of the center and I was looking for a ball more then a wave pattern. I do think it should be posable to suspend more easily and effectively with the magnetic sources but my question is more a matter of how I would go about doing that.

    Did you mean suspended particle in the cloud?

    Yes, a cloud of tiny particles, roughly spherical.

    @w3id0... what makes the north and south poles of a magnet is just the spatial and directional arrangement of the atoms in the "lattice"... nothing specific as "electrons" some here.... but yeah the spin angular momentum of electron does say "how much" the material is "magnetic"....
