There are no virtual particles associated with magnetic fields. There is only the fields creator, electrons. Photons are not related either, a photon is both an electric field and a magnetic field, remove one and it is not a photon. This is what I mean about assumptions, you are forcing a theory that is not valid onto reality, and then wondering why it doesn't conform.Bill_Marsden, I think you are correct, saying that "You still cling to the assumption that a static field is moving when it is not. Near as I can tell this is the heart of your lack of understanding"
But I guess one of the big reasons for seeing the Magnetic field as composed of virtual photons or at least in some way part of, is because according to QED, the force carrier is the Virtual photon. Also yes the electron or more precisely the charged particle is where the magnetic field originates. All QED says though is that the field is in reality composed of these Virtual Photons and these are what are responsible for all the interactions involving the magnetic field, even between something macroscopic like two coils.
about your statement " Following your logic there needs to be a carrier for an electric field, which is the inverse of a magnetic field." The carrier or as far as forces are concerned, there is and it is the virtual photon, I know weird but that is what QED says?
So I guess my problem is either not understanding QED, lol (more then likely) or Trying to combine two different views that just aren't easily combined, lol (also more then likely)

The quote comes from - http://en.wikipedia.org/wiki/Faraday_paradoxSome observations
Whether the magnet is "moving" is irrelevant in this analysis, as it does not appear in Faraday's law. In fact, rotating the magnet does not alter the B-field. Likewise, rotation of the magnet and the disc is the same as rotating the disc and keeping the magnet stationary. The crucial relative motion is that of the disk and the return path, not of the disk and the magnet.
This becomes clearer if a modified Faraday disk is used in which the return path is not a wire but another disk. That is, mount two conducting disks just next to each other on the same axle and let them have sliding electrical contact at the center and at the circumference. The current will be proportional to the relative rotation of the two disks and independent of any rotation of the magnet.
In an experiment done by A. G. Kelly shows there is a difference between rotating the disk only or the disk and the magnet. When the disk alone was rotated and the leads to the galvanometer were rearranged multiple configurations the reading did not change. However when the disk and magnet were rotated and the leads were rearranged, the reading was different for each configuration of the leads. Therefore, whether the magnet is rotating is relevant. This leads us to believe that the magnetic field rotates with the magnet.
Conservation of mass/energy would demand that the creation of a vitual photon be accompanied by the cretion of what might be termed a 'virtual anti-photon'. I would be willing to allow, for the sake of argument, that this 'anti-photon' would be identical to the virtual photon in every respect except the sign of its electric field. This would mean the net electric field of all the virtual photons would be zero, leaving only the magnetic field.....a photon is both an electric field and a magnetic field, remove one and it is not a photon.
Right, this is the point of my first post.I suspect this is the point BillO is trying to make. Without a rate of change in the field strength there will be no EMF generated.
Also the Maxwell in cgs.Last I heard this unit of measurement is the Tesla.
Therefore, whether the magnet is rotating is relevant. This leads us to believe that the magnetic field rotates with the magnet.
I suppose this will go on and on...
However, one finds this in Wikipedia The quote comes from - http://en.wikipedia.org/wiki/Faraday_paradox
What mechanism would cause a magnetic field to not rotate? Field lines frozen into the luminiferous aether? If the field remains attached to a permanent magnet when it gets displaced in space in every other way, why won't it rotate?
If it does not rotate, that's not a problem. I simply would like to find that there is some reason for it's being fixed in that manner.
That's what I said way back at the start of this post and the subsequent posters wanted to argue my point.Well I have pretty much come to the conclusion that we have no idea exactly what a magnetic field is, lol.
When the conditions make ever less sense, it's time to do something else.I'm not postulating it is fixed at all, not to the source, and certainly not to the aether. I'd rather it did not have, nor require, any frame of reference at all.
For what its worth, I also think this is related to the results of special relativity and the concept of an absolute speed of light, regardless of frame of reference.
Exactly? No. I'd have to agree with you. Not in the same way we can, macroscopically at least, say we know exactly what a chocolate bar is. This is science though, and science deals with hypotheses, theories and laws that explain some of the aspects, usually behaviour, of nature. It does not deal with exact proof or truth. Hypotheses are just ideas. Theories are formal hypotheses proven by how well they predict the observable. Laws are theories that are overwhelmingly supported by observation. Exact is a term for engineers to use and truth is for philosophers and clergymen.Well I have pretty much come to the conclusion that we have no idea exactly what a magnetic field is, lol.
Why are you taking this approach? This is the 2nd time you've been intentionally abrasive. I'd normally put in a formal objection to the moderators about souch behaviour, but I can see that would be fruitless exercise.No doubt as to the arguments. The following is simply ripe for it:
When the conditions make ever less sense, it's time to do something else.
And then later agreeing saying that work needs to be done.I think it may just be you on this one. How homopolar generators work is fairly well understood.
Again in post 20, you were responding to a post beenthere added.Did I not answer this?
You are being combative.Did someone say something different?
I have to object to your view.
I do think people are wrong about the magnetic field being attached to the source. However, I do not think I changed the conditions. Perhaps you misunderstood me. If you let me know where I did this, maybe can probably explain better.You have been changing the conditions as you go while expressing an "Im right, your wrong" style.
Correct. I'm not trying to develop my idea in this thread. I was just presenting it as part of my responses.It has nothing to do with developing an idea.
One of your first replies was telling Kermit:[
I think the two remarks are being taken out of context. Yes, homopolar generators are well understood. Yes, more work needs to be done to define the magnetic field. The two remarks are not inconsistent with each other.And then later agreeing saying that work needs to be done.
Yes, I defended my idea (that magnetic fields are not attached to their sources) and as I pointed out above, I did not and have not changed my mind. Regardless, and this is just a general statement, there is nothing wrong with one changing their mind. This is the whole reason for presenting a new idea and the ensuing debate and discussion.You combated everyone who replied just to end up changing your mind.
It has nothing to do with the website forum.[
Forgive me, but I do not believe you know what my attitude is. Maybe I need to use more smiley faces to get that across better.It has to do with your attitude.
Wes had asked a question to open the thread that I thought I had answered. It appeared to me as though he asked the same question again. I had thought my first response answered he question, that is why I asked that question. I think people might be trying to read too much between the lines.What was the reason for saying:
Again in post 20, you were responding to a post beenthere added.
Not intentionally. My query was in earnest. I was unsure if beenthere had been trying to make another point or possibly misunderstood your post or mine.He added it simply to add reference to the thread.
You responded:
You are being combative.
I'm not sure I understand you here. Where were others not wrong? Or more possibly more to the point, if the rest of you are right (and I am perfectly willing to discuss that) where was I wrong?Jumping in to tell people they are wrong when they are not.
Well, I am, but as I said already in this post, I am not developing it in this thread.You again end the thread by saying everyone else is the problem because the way you believe you are "developing" a new idea
Really? Where did I say it was proven?(Which you said was proof earlier in the thread).
Hmmm, okay, I can agree with this, but I do not think it applies in this case.I hate to tell you this, but typically when it appears that it is "everyone else" it is typically "you".
I am not sure I understand this comment. I do believe strongly in my idea (that magnetic fields are not attached to their source), but I know it is not yet proven. In fact, as far as I am ware, it has not yet been tested.If you had such faith in your belief that this was a well known, proven, stamped-sealed-delivered science, and you called people out, just to be wrong.
What, that someone has a new idea and that they stick to it?This ruffles feathers.
Again, I think you are combining several things. I am not sure which of the several ideas discussed you are talking about, but let me give it a guess.You cant go from saying that this is well known science, to "it is unknown" and "there is work to be done" while being so un-open to the fact that you were wrong from the beginning.
No, I do not agree. With one exception, no one discussed anything with me, nor asked me to address any specifics. The one exception was beenthere. He made a couple of points, which I addressed. He did not seem to like my response, but rather than provide a reasonable argument to it, he got abrasive. Or at least it appeared that way to me. I was going to address them further and give a more complete account of my hypothesis and where it stands in a new thread but I have decided this is probably not the best place for that.That is what caused the negativity.
I did do just that on this advice and my responses are herein.re-read the thread, beginning to end, knowing what you know now.
Well, I am sorry if it came across that way. I still do not think I have said anything wrong, unless of course that my hypothesis is wrong. It may very well be, but I've not seen anything yet to lead me to doubt it yet.You were acting like you words were the end-all, and when others posted, they were spray-painting on your wall of knowledge.
First, I do not think I asked for one. Second, to whom do I owe an apology? Finally, I gave one herein.You are the one that owes the apology.
Yeah (lol), strange, and sad, how that happens.Wow, this thread turned from What is a magnetic field to YOUR WRONG, NO YOUR WRONG Argument, lol.
You're welcome.Anyways I wanted to say thanks to BillO for the article, it was interesting.
If its benefits are clear and unclaimed and the steps to make it/design are not already in use (a genuinely new approach), regardless of how easy it is, you should be able to patent it. One difficulty I see with this is that a similar coil might have been used for something else. So the patent search might be tough. As an example, you might be trying to get a patent on just the coil for fast rise time, whilst someone else used it for another property as a component in a larger device. This is where a good patent lawyer earns their pay. I owned a patent (sold, expired, and now no longer required) on a small magnetic device, the prototype of which was built out of combining two existing devices but is was awarded by merit of exploiting the technology in a way that was never envisioned by the owners of the other patents. Make sure that you attribute as many purposes/properties to your new coil as you can. If any of those conflicts with another patent, they can be removed from the final application. Good luck with it.Also thanks to everyone else for all your input's, again it was interesting and informative.
P.S. If I have an idea for a Coil and it's actually an improvement on existing coil designs by a lot, then is it patentable? It doesn't really help much for our timescales but for like Nanoseconds and under, it helps tremendously with cutting rise times and fall times.
I kind of don't think you can just because well it's a coil, while it's not one you would normally think of, it's not exactly hard to make.
I am going to call a patent attorney but it's late and I am out of town so, maybe some of you might know until I get around to calling them?
Happy thanksgiving. If your traveling, don't let them touch your junk!Happy thanksgiving to all.
Billo, there is no wrong place to express a new idea. If it is correct, you will prove the nay sayers wrong.
It would be difficult for me to provide proof at this point. I would just be ble to provide supporting argument by example. There's no sources I can reference (not even on WikipediaStand up for what you believe.
Just make sure it is correct before asking it to stand up to scrutiny.
Scrutiny is what you have to deal with when challenging the norm.
If you have convinced yourself completely, you should have no problem holding out while convincing others.
The only people who complain about others responses are people who have no proof.
Most physical theories and laws have no absolute proof in any case, so they can always be disputed. Some easier than others. It would be nice to be able to come up with a theory that had a mathematical proof.After all, proof CAN'T be shown to be wrong.
