It probably detected a very impolite word embedded in your term. Try "snickers" instead. See? It does recognize "nickers".

I am asking Henry if he earthed his coils.
cogreslab said:OK Prag:
Let's start again from the top:
You said:
Firstly, you continue to make the ridiculous assertion that there is "no relation" between the electric and magnetic fields in a near field at low frequency. This is NOT true as I have explained repeatedly (and Hans too). There is a world of difference between the words "no fixed relation" and "no relation". The words "no fixed relation" indicates that the relation is dependent on other variables, such as the geometry of the emitter, and other factors as well. It does NOT mean there is NO relation at all. If the geometry and other factors are known, then it is perfectly possible to determine the precise relation between the fields. So you are wrong. The fact that you make absolutely NO apparent effort to actually CHECK and correct your misconceptions says volumes about the quality of your "science".
Rubbish! You are squirming about like (dare I say it), a worm on a hook trying to deny by means of sophistry that all those epi studies on the magnetic field can say nothing about electric field exposure.
Let me repeat it: there is absolutely no relation in terms of field strength between the electric and the magnetic field at ELF frequencies. The WHO say it; the NRPB say it, and nearly all physicists also say it.
Now tell us why we are all wrong.
I have news for you, Roger: It was the scientists who realized that Earth is round, clerics thought it was flat. It was the scientists who realized that heavier than air flight was possible, clerics who claimed that it was reserved for birds and angels. It was scientists who realized the dangers of X-rays, business-men (modern clericscogreslab said:*snip*
And btw, I don't believe any of you physics guys, because history has shown time and time again that you get it wrong:
"No, No, the world is flat, Galileo!"
Forget it, Wilbur, the idea will never take off"
"Oh no, it's perfectly OK to install x-ray machines in shoeshops, little boy"
and now:
"Sorry Rodge, there are still related magnetic fields in the leads, even when the electric kettle isn't being boiled".
Fortunately I don't take these physics theorists on trust: my instruments tell me there's no magnetic field there, but that there is an important electric field, as I showed earlier in this thread.
Go back to your 19th C theories, Prag, - I prefer the real, measurable world.

Now for trusting your instruments:
Measuring magnetic fields is quite complicated and requires a good theoretical understanding of electromagnetics in order to get useful results. This is because polarity, frequency, impedance, distribution, phase, interference, and noise can confound the measurements.
Measuring electrical fields is VERY complicated and requires a profound theoretical understanding of electromagnetics in order to get useful results. This is because electrical field measurements are even more sensitive to the factors mentioned above PLUS, unlike magnetic fields, it is virtually impossible to measure an electrical field without influencing it.
You have repeatedly shown that your knowledge and theoretical understanding of electromagnetics is very limited, and now you even scoff at such learning. In the hands of a lay-man, even the best instrument is likely to yield completely unreliable results.
Your latest disclosure, your applying a 32mV (where did you get just that value, btw?) to an open-ended wire and making assumptions about the resultant field shows just how poor your understanding of these things is.
How do you propose to be able to design experiments and evaluate the results when you have only the most sketchy idea of the theoretics behind an important part of of them?

I don't think so, Prag: it was the navigators such as Columbus, who daily saw the last thing to go out of sight over the horizon was the mast top, from which you have recently climbed down.
Baloney, the first one to suggest that the earth was round was Pythagoras, about 500 B.C. Later Anaxagoras used the shadow of the earth reflected on the moon during lunar eclipse as evidence for Pythagoras' theory. Later yet, in about 350 B.C., Aristotle suggested that the earth was a sphere, using the constellations in the sky you would see when you travelled away from equator. Some hundred years later the size of the earth was measured by some other Greeks (no, I didn't say geeks, I said Greeks).cogreslab said:I don't think so, Prag: it was the navigators such as Columbus, who daily saw the last thing to go out of sight over the horizon was the mast top, from which you have recently climbed down. Our Cristobal had done some long North to South passages before it dawned on him he could reach the Indies by sailing west.
Galileo, a scientist, turned up nearly a century later. and even he got it wrong badly on more than one occasion.

I was about to answer the above piecemeal, but it is too far gone. It is mainly technobabble. You happen to score a hit here and there, but I suspect it is more or less random.cogreslab said:Prag, I really can't beleive I'm reading your recent post:
"And what possible difference would that make?
I just KNOW I'm going to love the answer to this one! "
If you look under your sink or similar you might see an earth strap, put there by the electrician after wiring your home. It carries an aluminium tag warning householders not to remove it.
Unless you earth the metallic parts of an exposure system you will create eddy currents which give rise to electric fields. In homes the earth strap serves the purpose of collapsing any accidental short circuits and avoids the risk of electrocution. In a well earthed home the electric fields are less than 10 V/m. If the earthing system is deficinet the average fields can exceed 40 V/m. It is this level which can cause ill health IMHO.
cogreslab said:I am well aware of the difficulties in measuring electric fields, Prag, and by no means disagree with your comments there.
I'm sorry, but you are not. Your statements clearly show that you do not realize just how complex it is. I could lecture you for hours on elctrical fields, and you would still have more to learn.
That is why in our study I made sure we commissioned a professional engineer to construct and prove the accuracy of our instruments, which were supplied by Delta T Devices, a well established Cambridge firm, to calibrate them to NPL and cross check them, just as the UKCCCR did.
And here you prove my point; even the best and most precise instruments will not give you correct or useful readings if applied wrongly. Positioning of not only probes, but the instrument itself and any persons in the vicinity will strongly impact measurements.
We couldn't check the electric fields against the EMDEX instruments being supplied to the Wessex HA, because at that time EMDEXes had no electric field probes.
The precision of the instriment is not really that important. The correct application is.
The NRPB did however later (with difficulty) fit electric field probes to the instruments.
Oh? I thought you said they ignored electrical fields?
These difficulties in construction and proper siting using plexiglass stands however do not invalidate either our data or theirs.
This statement is nonsense. Difficulties in construction and making measurements do indeed not invalidate data, and that is not what I claim. It is how you HANDLE the difficulties that matter. And since you do not know how an electrical field behaves, you are not qualified to handle such difficulties, nor are you able to evaluate results obtained by you or others.

Cleopatra commented there was something rotten going on here, and she was right. Over the years I have meassured the electric fields in many homes. After reducing the electric fields in various ways the ill health symptoms often disappear.
How do you reduce electrical fields in a household? May I point out that feng shui people, eath ray people, and many others make the same type of claims. I don't suppose you have any evidence for your claim?
And btw, in the days of Galileo the clerics were just about the only repository of scientific and literary wisdom.
So you don't know much about history, either?
