I see what you mean. Each electron orbit is a closed circuit.
Does emf play some role in propelling an electron through its orbit? Scout "Bob Crantz" wrote The flux must cross a closed conductor (loop) for current to flow. But that is pertinent to a permanent magnet. Atoms have magnetic fields from the electron orbits. The electron is in motion around the nucleus in a closed path. The electron, through its motion, is a current and generates a magnetic field. If enough atoms are in correct alignemnt you have a net magnetic field. "Scout" wrote in message ... I thought the flux had to cross a conductor for current to flow. "Bob Crantz" wrote in message link.net... A permanent magnet does have current flow. "Scout" wrote in message ... "JG" wrote in message ... I believe the Swedes did a study that showed there were know ill effects on people, but I would pass on it if it were overhead. I believe their study was directly overhead. 200 feet probably wouldn't be an issue. More investigation is, of course, warranted. Makes one wonder about the magic magnetic bracelets and bands people wear for pain management. Why would magnetic flux be a miracle cure when produced by a permanent magnet but not when produced by current flow? Scout |

What a behind-the-times bunch of Putzes!
It has been proven electrons don't have an orbit. According to quantum mechanics, electrons only have probability of filling those areas around the core of an atom where the wave component of the electron can exist without canceling itself out. I hope this helps. CN "Scout" wrote in message ... I see what you mean. Each electron orbit is a closed circuit. Does emf play some role in propelling an electron through its orbit?

but isn't Bob's point that the electron is moving, and in doing so must have
a path, and hence, by definition, is electrical current? Scout "Capt. Neal®" wrote in message ... What a behind-the-times bunch of Putzes! It has been proven electrons don't have an orbit.

Negative! There is no current unless there is a conductor.
A conductor allows low-energy electrons to jump from atom to atom.

How about when a CRT fires electrons through a vacuum and onto phosphorus

Actually I do have a gauss meter (gaussometer?) on its way. I am curious to
know what the magnetic field strength is. My desk at work is about 3 feet from a large 480-240/120 step down xformer. I'm probably getting more from that than I'd ever get anywhere else. Once I get the meter, I'll do some experimenting and report back. Scout "w_tom" wrote in message ... Many replies are so full of urban myth that I must restart. Lets start with health effects rumored to be caused by electricity (and ignore that original study was later discovered with gross statistical errors). Many immediately assume danger was in high tension wires. They first failed to learn or demand the numbers. Those health effects, if exist, were more likely from something that creates stronger fields - such as wires underneath floor and inside walls, from circuit breaker box to central air conditioner. Those who jump to conclusions immediately assumed the study was about high tension wires. 'Those' include many news anchors who refuse to first do what all responsible anchormen are suppose to do - verify the story - hold the reporter's feet to the fire - do as Walter Cronkite did so routinely and so viciously. Immediately, the reply from many posters is suspect - having confused health risk warnings about something else - then assuming it must be high tension wires. They assumed as many irresponsible news anchors did on local news shows. Urban myth is now rampant even in this thread. We take it farther. Being an enemy of junk science reasoning, I first took a meter. I got numbers. Magnetic fields generated by an automobile dashboard may be higher that those from high tension wires. So you tell me where dangers exist? Already I am posting information that negates many of your replies. IOW too many people have 'knowledge' before they learn facts. They fail to temper their assumptions with numbers. Among the numbers not provided were line voltages. 128 kV? 230 kV? 765 kV? These also define other conditions such a noise. What is on those electric distribution towers? Bottom line. You need numbers before anyone can properly answer your question. Lets not forget, the original Scandinavian study that started all this hype was later discovered to have manipulated the statistics. This was discovered by other scientists who finally got access to the raw data. IOW hype continued until numbers were revealed. Any yet the speculation continues here - again without numbers. Too many never heard the whole story which is why they even blame high voltage towers rather than low voltage, high current wires. The original study blamed the latter. Therefore others here blamed the former. Wires with larger fields - that can even distort computer CRT screens in some rooms - should be of greater concern.

I know we have a few here who are knowledgeable in the field (no pun intended). Scout |

I know we have a few here who are knowledgeable in the field (no pun intended). I wouldn't live near HT wires. A few years ago I visited a power station. I swear that I felt something as I drove under the HT wires. I don't know what I felt. However, I was left with the feeling that I could tell when I was under the HT lines with a blindfold on. The voltages were 400k, and I only felt the effect 30ft either side of the wires. Regards Donal -- |

Scout - you are correct. To create an electric current, the
magnetic field must be changing. This is basic and fundamental to Maxwell's equations and should have been known to those posting permanent magnets creating electricity. Electrons moving inside 'shells' of the atom are totally irrelevant to electricity. Electricity means electrons move from atom to atom. It means the conductive path is a complete circuit. A permanent magnet has no moving field; therefore creates no electricity. Motion is also necessary. Furthermore note many half truths. Where are the numbers? Yes the sun can vaporize anything. Therefore we must keep everything out of the sun? Too much salt kills. Therefore the salt shaker should be treated as a hazardous material. This is how others promote hype and fear. No place do these fears apply to high voltage power towers. You would think from these posts that those high voltage towers subject the human body to 5 Telsa. In one cited study, 200 mGauss caused changes to cellular growth. That proves fields from electric lines will harm humans. Wait. That field is less than the earth's magnetic field. Therefore we are all being killed by the earth? This is the type of hype and fear being promoted. Worry. Where the wire bends, then fields are so much stronger? How much stronger? Trivial stronger. Again numbers would expose the hype. And hype it is. Posted is proof that all electric fields kill? Why do trivial fields from power lines kill when significantly larger fields (a decade+ larger) from the CRT do not? In another citation, field exceed 1 gauss before considered dangerous. So where is this 1 gauss field from the high voltage distribution line? It must be if the line is 230 Kv? Again, posted was fear without considering what actual numbers would be from that power line. So what is cited as dangerous? Because fields generated by a building transformer might be hazardous, then high voltage transmission lines also must be dangerous? Again, notice which electric lines are discussed. Not those high voltage transmission lines. Lower voltage, high current electric wires inside the building. Again there is this problem with hyping all electricity as dangerous only because very high magnetic fields MIGHT be dangerous. Ball park numbers. Long before the location is dangerous, a CRT or TV would have display problems. Now we have something concrete to consider. IOW we have a ballpark number AND some way to measure for that number. More interesting. What fields are really deadly? Magnetic or Electric? I wonder if those hyping fear even know the difference. But most shocking is some ridiculous idea that a motionless magnet creates electricity. Get the gauss meter. Take some measurements. Suddenly much of the hype being promoted here by some will disappear. Amazing what a few numbers can do to make so many previous posts irrelevant or misleading.
