Above is a link to a lecture series by MIT's Walter Lewin.  This is the first video in a series of 36 on electricity and magnetism.  He discusses in detail why some of the filings poles switch and why some do not.  I am now on video # 4 but, I have a weak math background so the going is tough.  I think you, or anyone, will enjoy this guy.  He does experiments at the end of each lecture.  Great stuff.

Nacl will respond to heat rise by creating electrical charge.  I believe it is called a pyraelectric substance.
They actually heatup crystals to get Mev potentials to drive cold fusion experiments.

Scotty, in the first experiment when you make the rubber hot, then bring the salt near it, and finally move the salt away and watch them jump, you are inducing an electric charge on the salt.  It doesn't have to be salt, this will work with small piece of plastic, paper, even metal filing.  Charge an object up, bring that charged object next to something that is "neutral" and at first the neutral item will be attracted.  Once the neutral item gets close enough, or touches, it becomes the same charge as the object it touched.  If you pull the object away, the newly charged item will now repel.  You can make motors and ringers based on this principle.

You should investigate electrets, they aren't too hard to make and pretty neat.  They are basically the electric field version of a permanent magnet.

I think that electricity is nothing more then a vibration that is created by a flow of resistance. I also think that magnets are only vibrations with different seeking poles. Meaning one vibration flows in one direction and the other in the opposite. The magnets core would just act like a antenna which attracts the vibrations.

@ Nightlife:

You should watch the video series I posted a little earlier.  They are done by Prof. Walter Lewin at MIT and address many of the aspects of this discussion.  You can then see how your theory might possibly fit into what is known about physics and electricity at this point in time.  They are very enjoyable to watch.  There are 36 videos dealing with electricity and magnetism alone, each about an hour long.  I am on video 4 and loving it.

Pirate88179, I read your post on that video series but for some reason I can't get use the link you provided. I meant to ask you about it before but I got side tracked.

 Is there something I need to download to be able to use that link?

Nightlife:

Yes, maybe.  I had to download realplayer as I did not have it.  I don't really like it and it is not set as my default player (which it tries to get you to do) but that is the only format it plays in.  Most seem to already have it, I had deleted mine but downloaded it so I can see these.  It should ask if you want to download realplayer, but if not, google realplayer and you can get it free.  Sorry I didn't say that before.  If this guy was not such a great lecturer, I would not have gone through the trouble, but it is worth it.  I hope you agree.

I did a search and found another site that allows me to watch them. Thank you and I see now who he is and i have seen some of his lctures before. I am glad there are more and I too will be watching them all.

 The following link is the one I am using.

I've worked with guys from MIT before, they aren't very imaginative and they like to steal your ideas :-\

Pirate88179, I am now on 8.02 Spring 2002 Lecture 9 and I have found a few things with in the ones I have seen that are not right and I believe that is because he doesn't understand them properly.

 So far this series does back my theory?s as well as the few things that he was unaware of happening such as the Faraday cage. that is just one of a few that I have came across so far.

 The thing about the cage is that he things we can hear him when he is in it because his voice is a higher pitch. That is not true, we can hear him because he is actually producing a vibration inside which creates a vibration on the outside of the cage. He cant get a vibration in, but he can get one out. His own lecture explained how that affect works but yet he didn't catch on. I think that is because of his closed mind on what electricity is and still assuming that electrons exist. If electrons exist, then they have to be vibrations. I am not sure how to clarify them as of yet but I am most definitely positive that electricity is nothing more then a vibration. his lecture confirms this with out him even realizing it.
 
This lecture proves how some book teaching take away some of your common sense. IMO.

 We should start a thread on this lecture series. I think we can learn a lot from it and not just by what is said but also by what isn?t and by what we find wrong with what is said.

 The more I watch them, the more the mathematical physics part makes sense. That?s scary. LOL When I started it just looked like a bunch of letters and it took awhile for it to kick in that they all have a relevancy.
 Just think of all the nightmares I will have now. My pies will start looking like mathematical pies, eye glasses will start looking like infinity, and my postings will all be coded by using just the first letter of words I use all the time. Nobody will understand me. Not that they do anyways. LOL
 
27 more to go. Do you think we can take a test after we get done and if we pass, we could get a degree from this course? LOL

@ nightlife:

I am really enjoying this lecture series.  Math is my weakest area so he loses me many times, but I can go back and look up symbols on the net and finally get what he is saying.  Yes, it would be nice to be able to take a test at the end but, the way I am going, I don't know if I could pass it or not, ha ha.  I am learning a lot which is fun.

Pirate88179, I did a search for "Professor Walter Lewin" and I found this.

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

 I am trying to contact him so I can talk to him about a couple of the issues I have with his lectures I watched.

@all

Cool page here .. i wonder what the picture resembles 
http://astronauticsnow.com/ENA/ena_rsi_1997.html

Its title is this      Energetic neutral atom imaging of space plasmas

From Some Pythagoras followers

It seemed clear to the Pythagoreans that the distances between the planets would have the same ratios as produced harmonious sounds in a plucked string. To them, the solar system consisted of ten spheres revolving in circles about a central fire, each sphere giving off a sound the way a projectile makes a sound as it swished through the air; the closer spheres gave lower tones while the farther moved faster and gave higher pitched sounds. All combined into a beautiful harmony, the music of the spheres.

This idea was picked up by Plato, who in his Republic says of the cosmos; ". . . Upon each of its circles stood a siren who was carried round with its movements, uttering the concords of a single scale," and who, in his Timaeus, describes the circles of heaven subdivided according to the musical ratios.

Kepler, 20 centuries later, wrote in his Harmonice Munde (1619) says that he wishes "to erect the magnificent edifice of the harmonic system of the musical scale . . . as God, the Creator Himself, has expressed it in harmonizing the heavenly motions."

And later, "I grant you that no sounds are given forth, but I affirm . . . that the movements of the planets are modulated according to harmonic proportions."

After my previous post  Would it now be safe to say that the "system were a part of is much larger than us and our "system of unity" is dependant upon the rest of the solar system as well .  Notice the feild lines that extend from the earth and go to the sun and ..who knows where else.. A magnetic feild line diagram of our whole solar system would be sure to shed some additional light on some mysteries here...
