Ahh Feldoh, thank you very much for this reference on the "Casimir effect". It's something I've never heard of before, but it seems to be a part of QED, more precisely aimed at this electromagnetic field business. I shall thoroughly enjoy reading it in more details, Much thanks to you Sir.

Heh thanks Pallidin, I did understand your first post, I tired to pull some sarcasm of my own.. guess I failed lol... Anywho, it seems like we might finally be getting somewhere with this post! my goodness. I really don't know how to respond to your question, however I will make an attempt at...

Ok Born, I get your point, "The magnetic field is a force that is produced by currents that acts on moving charges". So if I put a permeant magnet in a total perfect vacuum- no atoms or electrons at all. Then the magnetic field simply does not exist. The tree does not make a sound if it falls...

The very heart of the question is "what makes up a magnetic field"? The only reason we know they exist is due to the way they interact with normal matter. If we choose to remove all matter, how would we preform an experiment to quantify this field without subjecting the field to any kind of...

I think you missed some posts Cjames, or miss-read the very nature of the question.

Ok, so upon further research and discussions with some physicist co-workers, it appears as though the solution I'm looking for can be found in somewhat Dirac's theory, but mainly it's evolved form: Feynman's QED theory. I'm still not in full understanding of it right now, but if what precedes...

Ok so this magnetic field will exist in a theoretical perfect vacuum even without an observer, or matter of any kind for it interact with. That's great, although I'm still not overly convinced. I was really kind of hoping that someone would have posted a real good though experiment to prove it's...

Hmmm, perhaps that's the right idea Dale. The magnetic field is only made up of what it interacts with... There is a real possibility that the very logic is which I'm trying to envision these fields is fundamentally flawed, and that they have to be thought of differently.

Well yes, but that's kinda different... Isn't it? these EM waves we call light. A traveling packet of energy. An EM wave is just an EM field moving in space and time?... but the only way to get a magnetic component to the EM field is to have a varying E. field traveling through space and time...

Well, there is no real way to see if these fields exist in a perfect vacuum without altering or disturbing the outcome of the experiment. You see, if want to see if there is a magnetic field, you have to insert particles to the Perfect vacuum thereby making the vacuum not so perfect anymore. I...

Hi, So this question might be a little simple, or not. But I was wondering about the exact nature of magnetic fields. Now obviously magnetic fields work in a vacuum(due to the fact that it's not a perfect vacuum), but would a magnetic field exist in a theoretical perfect vacuum? Now I think...
