Why do cows /sheep & horses stand under electricity pylons when it rains?

Now, that being said,,,,,,,
Why is it that when they do stand under the pylons they usually stand facing all in the same direction and in a line????????/
Life is great for me... Most of the time... But then I meet people online... Very few are real friends... Many say they are but know nothing of what it means... Some say they are, but are so shallow...

Well, humans aren't sensitive to magnetic fields and I don't see any reason why cows would be. I reckon the most likely thing is that they are all imitating each other -- the herd instinct.
Perhaps the reason they stand under power lines is that they're too stupid to notice they don't afford any shelter.

Whilst not wanting to set off any alarms, there are plenty of sites that talk about various animals /birds sensitivity to magnetic fields. It is believed to be the reason why birds can migrate around the globe and return to exactly the same place they were last year. Here's just one by well known Australian science commentator Dr Karl
http://www.abc.net.au/science/k2/moments/s150891.htm
Perhaps the sheep/ cows can detect something from the magnetic field surrounding the power lines.

Ah, yes, but cows are mammals, birds are birds, and while birds have an evolutionary reason to want to navigate magnetically (so they can use the earth's magnetic field) cows don't. Cows don't migrate (at least, domesticated cows don't) and they live in land so can navigate by visual clues if they need to. Beyond migration, I can't see any evolutionary point in lining up according to a magnetic field, especially incidentally and when they're locked up in a field.
Cows aren't famed for their navigational skills. I think it's a leap of faith to assume that they have a "sixth sense" for it -- because if they do it evidently doesn't work very well! Humans certainly don't have anything along those lines.
So, I don't know the answer -- I have never seen this power-line phenomenon, and I'm not sure if it even really exists or not -- but if it does I don't think it has anything to do with magnetism. If I had to guess, I'd reckon that it's a mixture of herd instinct and maybe the instinct for shelter.

I can't say I've ever seen cows standing under electricity pylons when it rains, but the Oxfordshire Cotswolds countryside that I know best does sheep not cows. The farm in Windsor Great Park that my grandfather ran for many years had beef cattle, but was free of electricity pylons ...
However, I don't discount the existence of the phenomenom. Pehaps there's some intermediate effect? I know that high-voltage lines can make a wide variety of musical notes in heavy mist or light rain ... one place that I stayed regularly in Fife was a narrow valley at foot of Loch Leven, and the power lines used to moan eerily when the early-morning winter fog closed in!

Deeej you say "Well, humans aren't sensitive to magnetic fields and I don't see any reason why cows would be."
That is a sweeping statement which may not be true. There are places where there are strong magnetic fields where one can be strongly affected by it.
http://www.mysteryspot.com/
I didn't say cows were using any sensitivity to magnetic fields to navigate
"Cows aren't famed for their navigational skills. I think it's a leap of faith to assume that they have a "sixth sense" for it -- because if they do it evidently doesn't work very well! Humans certainly don't have anything along those lines."
What I believe would be more correct to say is at the moment we are not able to measure a sixth sense in humans with the current technology.

Re California's Mystery Spot... read history on their site
I have been there and felt the weird feeling that one can get there.
It is reported that wild animals, insects and birds rarely ever venture into the area. They don't know if this is due to the magnetic field but a compass will go berserk. It has also affected the growth of trees in the area (some growing in a corkscrew fashion.)
Not sure how relevant any of this is to the thread.

Aussie, just use the "quote message" option and then edit out whatever you don't want in the way you would edit in a word processor. It's that simple.

Aussie,
>What I believe would be more correct to say is at the moment we are not able to measure a sixth sense in humans with the current technology.
Sort of. That is true, but it gives the wrong impression -- that there is a reasonable chance that a sixth sense exists. If such a thing existed -- even if it could not be picked up by a machine -- a test could be developed to investigate it. Even a scientifically rigorous double-blind trial, conducted through the use of varying magnetic fields, multiple volunteers, and detailed statistical analysis. The same, incidentally, goes for nearly all "supernatural" or unexplainable phenomena, if the parameters are set and enforced very carefully. But no-one has ever produced a trial along those lines in humans that both stands up to scrutiny and shows anything unusual, so far as I know.
>Deeej you say "Well, humans aren't sensitive to magnetic fields and I don't see any reason why cows would be." That is a sweeping statement which may not be true. There are places where there are strong magnetic fields where one can be strongly affected by it.
Again, I'll believe it when I see it. I appreciate that just because there is no known mechanism that we know of this is not a reason to ignore the possibility entirely, but, again, there is no evidence that it is the case. It is an equally sweeping statement to say that there are places where one can be strongly affected by magnetic fields without qualifying it by explaining to what extent the presence of the field is known to subjects.
Anyway, what is a "strong" magnetic field? Those found in nature are many orders of magnitude smaller than (say) an MRI. I've had an MRI, which has such a strong magnetic field that it will tear a magnetic metal implant out of your body, yet I felt nothing (apart from the vibrations of the machine and a little claustrophobia, which is perfectly natural in the circumstances. The claustrophobia started before they switched the machine on).
>Re California's Mystery Spot... read history on their site
>I have been there and felt the weird feeling that one can get there.
It is certainly demonstrable fact that if you tell someone, "We're in a strong magnetic field here. Can you feel it?" they are more often than not going to be able to feel something. But this is because of the power of suggestion, and it applies whether there is really a magnetic field there or not.
I get funny feelings all the time because of changing hormone levels in the body, and I'm tempted sometimes to blame them on the surroundings. In some cases, they may be -- indirectly -- affected by them but that's because of a psychological response to inputs from the eyes, ears, skin etc. I also get exactly the same feelings sometimes when I'm in comfortable surroundings at home, and yet there is no attributable physical reason for them.

Nope. The cables have electric current flowing through them (which precludes static), and the rest of the structure is earthed.

how about hum at a frequency at about 19khz and well above for animals to here.? :-/

|
|
|
|
|
|
|
|

Well -- I don't know what the alternating frequency is on power lines, but assuming it's 50Hz (as it is for standard 240V power) then if it made a sound you'd be able to hear it easily. In fact, it is possible to hear a hum in damp weather; I'm not quite sure what causes that. Presumably the alternating current is affecting the air or the water droplets in some way.
I do not think there is any reason for a very high-pitched hum (19kHz+) -- to do that you'd need a frequency in that range, and it's nearly three orders of magnitude higher than 50Hz.
Why animals would be interested in a hum, either low-pitched or high-pitched, beats me, though -- it really doesn't sound terribly likely. Even assuming they are, it's very difficult to line up to a sound, facing one direction only.

Er, no: a 19kHz alternating electric current is directly transferred into a 19kHz sound wave if there is some mechanism for it to do so. That's how a speaker works -- it directly converts the signal as described by the current passing through it directly to sound.
You often get interference at 50Hz on sensitive audio equipment -- this is known as "mains hum". You can hear samples here:
http://en.wikipedia.org/wiki/Mains_hum
In a power line, the only thing alternating is the electricity -- there is nowhere else a signal or noise could come from.

Earthed = grounded.
It means static electricity cannot build up because it would leak away into the ground.

i agree with you.
all metal work is earthed so that no difference of potential can exist,
this is a legal requirement in this country.
by earthing it will ground all spikes etc which includes static and any mains voltages. i.e. a difference of potential will not exist.
now lets get back to the cows.:-/

There can be frequencies other than the 50hz (or 60 hz in the US of A) on the power line. They are used for switching purposes on the grid. Also a frequency can be converted directly to sound with a spark or corona. This is a spark transmitter. Works very effectively on a damp or foggy night.
Now what about the cows?

Cow Tilting......
Well, like I mentioned earlier, cows tend to stand in line as if in ranks for inspection. Another fact about cows is that when they drop to the ground they always have their legs under them so they can get up easily.
Cow tilting is accomplished by first enlisting the help of 3 or 4 big boys....... They then carefully sneak up to the first cow in line and when close a signal is given and they jump up and charge the cow. They broadside the beastie and knock it over.
If this is done correctly, there is a domino effect causing the entire line to tumble.
Now, as I meationed above, cows like to have their legs positioned under them and when they hit the ground without legs under them they begin flayling about getting the legs into the correct position so they can once again arise.

I disagree,
I think the cows move in the direction of the strongest tingle.... they do this in the hope that the tingle will increase to a genuine pulse.......

You might think so.....
But it is really funny to see.....
and believe it or not.... when the cows arise they reform into their ranks as before....
Either they are very very very stupid or they like the game....

None of those links satisfactorally explain the way mystery spots work fully. I can understand the bit about tilting the room or altering its shape so that from the inside the brain is fooled and hiding the fact that the site is on a hill to heighten the effect. In the case of Santa Cruz there is no attempt whatsoever to hide that the track up is on a steep incline and the cabin is tilted. All the links have also ignored the spirit level (are they using dodgy ones? and the effect that people get whether or not they go in the cabin.
Some felt a bit woosie in the head, dizzy or nauseous.
It was reported that classes from Universities have conducted experiments where they have hung tarpaulins to hide the visual effects (of the tilted building )but it has made no difference to the phenomona.
The only thing I can suggest is you go there and experience it for yourself.

If you can find out which university it was -- and then find out what their conclusions were -- I would be much interested. Whatever you might say, Aussie, these are tourist attractions foremost and therefore those who run them are not beyond exaggerating or even wildly bending the truth for effect.
I do not say that the phenomenon does not seem real (and I am sure I would be impressed by it if I went to one of these places), only that it has a very rational scientific basis.
Unless you brought the spirit level with you I would be very inclined to mistrust it, yes.

Oh, and Aussie, you say,
>None of those links satisfactorally explain the way mystery spots work fully.
Maybe, as far as you're concerned. But which is more likely -- that a tourist attraction is using a piece of trickery of which you don't know the full details (especially considering that similar effects are well-documented) or that they have somehow hit upon a real phenomenon that transcends known science altogether, yet cannot be demonstrated in proper test conditions?
When you see a conjurer perform a clever magical trick (let's say a feat of telepathy) to which you cannot work out the secret, do you immediately assume that he must have been using a genuine "sixth sense"?
I hope I don't sound patronising -- I'm not meaning to; I'm just suggesting that the situations have more in common than you might realise.
Personally, I find magic tricks all the cleverer because I know I'm being deceived but I can't work out how.
