if the magnetic poles change anything electric would reverse and planes would fall from the skys ....is this true ,i know that there is evidence that this has happend before ...thanks jane.???????please help xxx

Earth's magnetic field constantly fluctuates to some degree (it's weakened by about 10% since the 19th Century), but the majority of geophysicists see no hard evidence that the field is about to reverse like it's done in the past.\n\nEven should it reverse, the whole cycle takes thousands of years, and still would have little effect on our electrical power systems. Nor would planes fall from the sky, although reliance on magnetic compasses would have to be adjusted.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

It doesn't just happen all of a sudden, as OBIWAUGH pointed out, the movement of air caused by the storm causes the clouds to acquire a polarized electrical charge that by nature has to release its energy.\nThat energy is the lightning bolt reaching out to an oppositely charged object to balance the energy.

wow...in 1968 i watched what appeared to be a shiny metallic piece of  crumpled metal tumble towards earth for 10 minutes, it was probably space debris or toilet ejecta from a passing airliner.what you seen was likely hardboard insulation like they use on construction sites, that stuff will fly a long ways with little wind....or else it was a runaway magic carpet

as far as i know of, yes.\n\nthink, the man made magnets create their own magnetic field and have always been exposed to the earths magnetic field. Reguardless of the man made one's position, they still emit the same pull towards each other based on their own magnetic fields. Just like magnets work in outer space, they should work at the north and south poles. (also, the man made magnets pull isn't effected when you connect multiple ones together so off of this example, they should work at the north and south poles also.)

What I am about to tell you is fact i don't care weather or not you believe it i just wanted to share it with others.  \n\nComing out of wallmart, I had bought signs cause I am a huge ufo buff.  well as i was getting into the car and telling ym mom about th emovie we see a bright light in the sky and it just screams off to the right fster then anything could possablely move.  i am talking this thing was in open sky high above us and in 2 second went from over head to the horizon, at least 20 to 25 thousand miles per hour maybe more.  We were both shaken for a minute then decided to watch signs a few weeks after.\n\nBiggest coincidence I have ever had

their is one in (north burlington ontario) as well  .I have also read their is one in  Oshawa ,ontario, If you go to the bottom and place your car in neutral it drags your car uphil slowly .\n____________________________________________\nscientifically it is an optical illusion \nSometimes you may find or hear of a mysterious place where objects can apparently roll uphill. This is a remarkably common illusion which is found in numerous locations around the world. Usually it is a stretch of road in a hilly area where the level horizon is obscured. Objects such as trees and walls which normally provide visual clues to the true vertical, may be leaning slightly. This creates an optical illusion making a slight downhill look like an uphill slope. Objects may appear to roll uphill. \nSpots where the illusion is especially powerful often become tourist attractions. Tour guides may like to claim that the effect is a mystery or that it is due to magnetic or gravitational irregularities or even that it is a paranormal phenomenon which science can not explain. This is not true of course. Natural irregularities can only be detected with sensitive equipment and cannot account for these places but science can easily explain them as optical illusions. \n\nThere are several things which enable us to sense which way is up. The balance mechanism in our inner ears is one system we have, but visual clues are also important and can be overriding. If the horizon cannot be seen or is not level then we may be fooled by objects which we expect to be vertical but which aren't really. \nPeople often overestimate the angle of a slope. If you are standing on a slope of 1 degrees it will seem like a slope of 5 degrees. Because of this effect the anti-gravity illusion can seem stronger than it should be even when you know the cause.\n\nEven when the true cause is understood it can be difficult to believe. If you think there is a magnetic anomaly just use two plumb lines, one made of iron and one of stone. They would hang at different angles if a strong magnetic field was acting horizontally. \nHowever, it is not always easy to demonstrate that a slope which appears to go uphill is really going downhill. The only reliable way of determining the true horizontal is by careful surveying. If a good topographical map of the area is available it may be sufficient to show which way the land is really sloping. The results will confirm the illusion. \n...\nyou can also check the info I found on the Oshawa site \nhttp://www.shopinoshawa.com/magnetichill.htm

Very impractical for at least two reasons:\n\n1) It would have to be an unbelievably powerful magnetic field to generate any significant lift. The Earth's magnetic field is very weak.\n\n2) As soon as it left the ground the vehicle would be trying to flip over to an attitude where the Earth's magnetic field attracted it. You can't have a south magnetic pole without a north one and vice versa. As soon as this flip happened, the vehicle would crash back to Earth hard.

none of the answers is correct , actually magnetic lines of force will be acting in anticlockwise direction.

Unless you are exposing this magnet to CRT (display tubes like TV's or computers) I doubt that much will happen. DO NOT take it aboard anything that relies on a compass for navigation!  IF you need a box to store it in that will allow very little magnetic waves to escape, I suggest a soft iron box, or...couple the NORTH pole of the magnet to the SOUTH pole of the magnet with soft iron...that will get rid of most stray field. Sounds like a lot of work unless you really need this magnet.

It would be so helpful if, when providing proof of something, there was actually a whit of truth to what you have to say.  Not only is most of what you've said untrue, it simply doesn't make sense.\n\nHowever, not being one to just say that and not back it up.\n\n1)  A planet sized comet wouldn't be generating a large magnetic field because comets are made of ice and (mostly carbonaceous) dust, two things which are most notably not magnetic.\n\n2)  No scientist worth his salt yet has indicated there's any evidence of massive "plasma scarring" on the surface of Mars, and if one did, it would be from plasma hitting the surface of Mars.  While the Sun and other stars are made out of the stuff, comets completely lack it and magnets don't create it, even if one magnetic field comes into alignment with another one, which brings us to...\n\n3)  Mars has no significant magnetic field.  It has a few magnetic patches on it where there is probably quite a bit of iron concentrated, but it's not magnetic in the least (as a whole planet, in the fashion of, say, the Earth).  It has no magnetic poles, either... and since you can't demagnetize an object with another magnetic field, it couldn't have ended up that way because another magnet "stripped off" it's magnetic field, and in any case you've said Mars absorbed all the energy... so it should be absolutely glowing on the magnetic front, and it isn't.\n\nSo, your theory is that an object which we know has no significant magnetic field (Mars) and an object which we know cannot have a magnetic field (a comet) got together and flipped magnetic poles which didn't exist when you said this event took place, in this massive magnetic tango that produced a product it could not have produced (plasma), that literally fired right through Mars like a gun and, even though it shot straight through the core from one non-existent magnetic pole through the other, didn't destroy the planet from the inside out, but left it completely in tact and just burned off the northern hemisphere, totally defying just about every one of the Laws of Physics God created the Universe to run on because, perfect being that He is, He was too incompetent to get it right the first time and needed to make a trial run which, as a compassionate and merciful God, He decided to burn to a crisp and roast alive every living thing on rather than allow to live on in peace once it had served His purposes, because He just didn't feel bothered to have them around any more.\n\nYou're right.  That's a freaking miracle.\n\n\nP.S.-- Craters naturally fill in from the center out because the edges of the crater are protected by the wall, leaving the center of the crater where dust can be most easily blown and settle, and there are dust storms on Mars.  Also, cooling cracks are very regular things, as the contracting matter pulls evenly away from the weakest point, most often causing the split to be very even and straight.  There's nothing about those features on Mars (or the shield volcanoes, for that matter) we haven't seen happen endless times on Earth-- and directly witnessed in other planetary bodies in the Solar System, which is why we know what made them.\n\nEdit:  All right, let's do this.  First, as for comets:\n\nhttp://www.windows.ucar.edu/cgi-bin/tour_def/comets/comets.html\n\nhttp://www.solarviews.com/eng/comet.htm\n\nhttp://solarsystem.nasa.gov/planets/profile.cfm?Object=Comets&Display=Kids\n\nEveryone from the sixth grade on but you seemed to learn in science class what comets were made of, and most of us quite a bit sooner.  They're made out of ICE and DUST.  Because of the severely black color of them and our analysis of the gases in the comet's coma (you know, that big gas cloud you see around the comet that, oddly, is made out of ice and dust), we're pretty darned sure a lot of that dust contains CARBON, so they're made

Sounds like a question i'd ask Doc Brown on Back to the Future, what happens when history is changed?  Playing with the space time continuum is risky business.  Have you heard of the Chaos Theory?  Any little event can cause major ripple effects that may be worse than the one that was 'supposed' to happen.  For example, you kill al the terrorists who flew into the WTC and Pentagon, which means there was no stopping of commercial airline traffic....which means the terrorists on the west coast were able to carry out their suicide missions...which means one of them struck a nuclear power plant that released radiation travelling world-wide.  You get my drift, and, oh by the way, there were terrorists who were ready to takeover aircraft on the westcoast, but thanks to the FAA clamp down on traffic, their plans were thwarted.  Their targets are unknown, i only picked a nuclear facility to make a point.

The magnetic poles have changed many times throughout earths history, and we still have the moon. Also, the moon has nothing to do with our magnetic poles. The Moon is kept in orbit by gravity, which is a not a property of our planets magnetic poles.

Any two magnetic fields will interact with each other. The same happens with the Earth's magnetic field and a magnet, although the Earths magnetic field density is very weak in comparison to a magnet. \nThe magnet will locally distort the Earths magnetic field, which can be seen by looking at a compass in just the Earth's magnetic field, then looking at the compass when a magnet is brought near.

I don't think so. The Earths magnetic field is generated by the dynamo effect of the solid Ni-Fe core spinning at a different rate to the liquid Ni-Fe core around it. I can't see how humans can effect that process.\n\nI guess it might be possible to modify the magnetic field locally be producing another field that interferes with it....but I doubt we're doing anything strong enough to do that. The polar shift of the magnetic field is a natural process that has occurred thousands of times.\n\nTo answer 'my girls' question...the earths magnetic field protects us rather than harms us. If it didn't exist, we'd have little protection against the harmful radiation produced by our sun.

You haven't kept up with the latest scientific\ndiscoveries.  Recently, well, in 1887, Albert\nMichelson and Edward Morley proved that no\nmedium (then called "ether" or "aether") was\nneeded for the propagation of electromagnetic\nradiation.

I'm entertaining the hell/purgatory theory and the (reletively) simple theory having to do with the magnetic field on the island. I'm leaning towards the scientific theory, that all this crazy stuff happens and people are affcted by and because of the magnetic field.

As a pilot and a Geologist, I find this highly unlikely.  \n\nThe first consideration is the media through which the wave are transferred.  Consider this simple experiment.  If you wave your hand through the air, the wind generated wouldn't be felt by someone on the other side of the room.  Air is a terrible transmitter of vibrations.  It tends to dampen most vibration.  Now consider that the plane was several miles in the air, it seems highly unlikely that the plane would have felt the effects of the quake.\n\nSecondly, Geologically speaking, earthquake waves tend to radiate out from an epicenter and are likely never felt at the point exactly opposite the epicenter on the earth's surface.  The Iron-Nickel core dampens the shock waves of the quake to the point where waves simply never appear on the opposite side of the earth.\n\nThird, there are no alarm signals in a plane to indicate that the earth is shifting.  \n\nFourth, the plane was landing to make a refueling stop, and so was low on fuel already.  Most sources point to a running out of fuel or fuel system malfunction as teh likely cause of the accident.  \n\nFifth, the article to which you refer first appeared in the Russian equivalent of the National Enquirer or Weekly World News (Grocery Store Scandal Magazines).\n\nThus, when flying there is little to fear from the quaking earth below you.  In fact, you're probably safer where you are.
