  1. I'll be off line for awhile but I'll be back to take up your latest post in a few weeks, kimmy. Talk to you later. Have a glorious day!
  2. We're getting to the end of this pretty soon. Here's a situation for you. We have two masses, M1 and M2. M1 is a mass equal to M2. The difference between the two is that M2 has magnetic propertiesWe put M1 or M2 on a rotor and use some energy to get the rotor rotating that takes X amount of energy, because the two masses are equal the energy necessary to turn the rotor should be equal. Now we place a coil with an iron core next to M1 as it rotates and nothing happens. We place the same coil with an iron core next to M2 and we get an electric current generated in the coil. The question
  3. Well, when you say that "putting current through a wire with zero resistance creates almost zero energy and generates almost no heat at all" I have to wonder if you have my interests in mind at all? It looks like the kids have chimed in and they seem well up on things. I guess they aren't as stupid as you believe.
  4. That small amount of energy that aligns the electrons should mean a reduction in a difference of potential, that is the magnetic force, but it doesn't the same force exists as existed prior to the alignment. Gravity is a force, that is a difference of potential and thus, against the theory of relativity, is a source of energy that never depletes. Magnetism is a similar force that is a source of energy that essentially never depletes. The absence of dark matter may mean the unraveling of relativity theory. It is not for my benefit that you go through this exercise. Of that I am certain. A d
  5. It does sound like it. Of course it is, the energy is necessary or else no magnetic field is generated at all. However, the energy is necessary and is converted to electron aligning to produce magnetism and that is converted to align electrons in a ferrous material such as a spring. Energy is never consumed. Unless Einstein was wrong? I think there are a few Physics teachers that teach energy can be consumed, perhaps yours did? Power companies use the term consumed as in how much you converted to different forms. When one turns on a light one says he is consuming energy. In actual fact h
  6. It does indeed take energy to move the electrons and bend the spring and hold it with an electromagnet but doesn't appear to need to move any electrons with a permanent magnet in order to bend the spring and hold it.
  7. No one knows why a permanent magnet exists in nature. The properties of magnetism are indeed well understood. It wasn't so easy to prove the world was round a millenium ago. Evidence had to be gathered to prove it. Traveling around the world took too long and was fraught with too many dangers. The idea of a flat Earth ended for most of us around the end of the 1400's.
  8. That's all correct Peter. Here's the point. No one knows why a magnet exists in nature. We can make a magnet by running electrical current through a coil around an iron core. The magnetism exists as long as the current is going through the coil. The electro-magnet pulls on the spring. Work is being done. As long as current is going through the coil the spring is being bent. A permanent magnet pulls on the spring in the same manner but no energy is being expended. It is similar to me not having to eat to stay alive. Having some kind of permanent unknown source of energy to keep myself e
  9. I don't think so. Magnetism is a molecular force that changes the molecular alignment of particles only in a ferrous material - at least that's the theory. Spaghetti acts the same no matter what material you throw it at. If spaghetti sticks to the wall by the exact same electromagnetic interactions that magnets do then magnets would stick to the wall as well.There is no explanation for why magnetism exists. Spaghetti sticking to the wall, glue, a block sitting on a table are all gravitational phenomena and not electro-magnetic phenomena.What kind of scientist are you? All right. I know how
  10. There is no need to uproot the present because someone is rooted in the past. We need to move on. No one in present civilization has directly experienced injustices of a century ago and they never will. Are there still injustices? Of course, but hopefully we have made progress. Is it the right of those descendants of those who experienced past injustices to inflict injustices on the descendants of the past oppressors of earlier generations?
  11. You are just being obtuse. Cooked Spaghetti sticks to the wall because it is sticky. There are normal and gravitic forces and mass properties that explain that phenomena. There is no actual reason that explains why magnets exist. There is an understanding of them from different views, the Newtonian view and the quantum physics view are both different. Read about that here. http://sunearthday.gsfc.nasa.gov/2010/TTT/71.php Now grade ten physics is not going to explain magnetism except as kimmy has explained it here. For practical purposes it is explained in our grade 10 physics. Cer
  12. I will try and make it really simple for you and the kids.A magnet in proximity to a metal spring will attract the spring to it. This is how a contact works in an electrical circuit. The proximity of the magnet bends the spring and there is a contact closure. As long as the magnet remains in the proximity of the contact the spring contacts remain closed. The metal of the spring tries to return to its normal position but as long as the magnet is in proximity to it the spring is held in place. Of course it takes energy to move the spring and close the contacts. Like an elastic there is always a
  13. Normal force is holding up the mass of the magnet? Is that what you are saying? "A magnet under the beam has no normal force exerted upon it to hold it up." Is what I said. There is no extant upward normal force applied to the mass of the magnet. Excellent that you find definitions important. Just above didn't you answer normal force was holding the magnet up?The normal force (downward) in your equation is only a reaction to the normal force of the mass of the magnet applied upward by the attraction of oppositely charged molecuales created by the magnetic force so they essentially balance. If
  14. Thanks squid. So in the non-scientific context the big bang theory is something unproven or speculative. As used in science, it is an explanation or model that helps to explain and predict natural phenomena. It doesn't exclude the possibility of other theories and as long as there are unknowns it remains a theory. There are currently two "theories" that are of practical or scientific use in physics, they are Newton's gravitational theory and the theory of relativity. Non-scientifically speaking then they are speculative. Scientifically they are models or concepts that explain and predict n
  15. The kids? I know so you can love them and hold them and pet them. The theory of relativity is accepted as fact by a lot of people and that is the problem. You were asking for what anomalies there were in the theory earlier and there are quite a few. The search for dark matter is essentially to explain one of those anomalies, where all the mass is that the theory says should be there. The Higgs-Bosun particle should exist according to theory. Physicists at CERN believe they may have discovered one last summer, more testing is being done. Quantum mechanics, string theory, dark matter all the
  16. What? And make the most important job of all irrelevant - that of the bureaucrat. The era of Bureaucratic Empires coming to an end? It really is the Apocalypse.
  17. I have been polite to kimmy. I encourage her to keep informing others of how wrong I really am.For yourself, I must say I am a bit disappointed but not entirely surprised at your position. I've gotten kimmy to at least agree that energy is necessary to align the electrons of a ferrous material in order for the magnet to adhere to it. It is also necessary to hold those electrons out of their normal state for as long as the magnet is in contact with it - that takes energy. I am not surprised at your position because it is impossible to proceed with a theory unless the theory is upheld. Mathema
  18. This lesson on how Blacks took over Detroit is a good one on how Blacks can entirely take over America.
  19. You are right. They are not intended for any specific sector. They are intended for everyone. Boges points out some very valid points from a conservative economic view, that being there is a specific purpose and an intended specific sector for a minimum wage. He doesn't realize that the Liberal view is that everyone should make that wage and no one should make more. It's called equality and social justice or, correctly - Marxism.
  20. Not if he was right. The whole purpose of the current economic structure is stability and that requires predictability both of the policies implemented and the market forces themselves. Predictability is a valuable commodity and it depends upon correct analysis of information. Spinelessness and foolishness? Or a system out of control? The fact is they created a boom which always results in a bust and that means a crisis for government revenues resulting in deficit spending and increased debt as they try and pump up the economy with new money. The boom and bust cycles are getting incre
  21. I'm sorry to hear that Russ. I think the discussion is important. People really need to know about the central banking system, what money is and all that. I was reading about the Bank of Canada on Wikipedia this morning to see what happened in 1974 and why the big push from COMER is to return to the days prior to 1974. I guess essentially inflation is what happened. The loans the Bank of Canada made prior to 1974 were not entirely interest free but loans wwere made for as little as 1%. This policy was cited as being responsible for high inflation and consequently they decide to slow the gro
  22. So what is the applied force that must be strong enough to create the friction. You just refuse to understand what I say. "Normal force is *always* perpendicular to a surface." is what you said. I said, "normal force on a perpendicular surface is zero" By perpendicular surface I mean perpendicular to the ground. It would perhaps have been better for me to say "normal force on a 'vertical surface' is zero" No Once again, I believe you misinterpret what I say. Do you think I meant no normal force when a magnet is sitting horizontally on top of a beam? There is no normal force from a ma
  23. That's precisely right. Obama certainly isn't being Presidential, both he and the Attorney General Eric Holder are being the community organizers they have always been, being divisive and setting the stage for protests and demands for equality. It sort of sets the civil rights movement back to the 60's. It's as if the US has not made any gains in eliminating racism at all. They did get rid of the laws that held racism in place through segregation and second class citizenship and it took these fifty years to get to where they are now, a far cry from the sixties but still with a way to go. I
  24. Well, Russ, the whole central banking system was created to bring monetary stability to economies. Establishment of the Federal Reserve in 1913 (marking its centennial year this year)was a major turn in global finance. But what does a central bank do? The Royal Canadian Mint actually prints the physical currency we use and call cash.<br />The US Treasury prints the US currency. What does the central bank do? It does regulate the banking industry in the nation where it exists. It sets the interest rate and the reserve rate and the currency supply thus regulating inflation. It essentiall
  25. Hi Russ, I have a few questions about your post. I read a little bit of Mr. Armstrong's website but maybe you can point me to the place where my questions are answered. Firstly, you say Mr. Trudeau moved Canada from "having a public debt (printed money from the Bank of Canada) to borrowing money from private banks and issuing bonds (money) that pay interest?" As far as I know the Government has always sold bonds to Canadian Citizens and private interests that have paid interest to the holders of those bonds - Canada savings bonds and such? Is that not true? I have read more about the
