Is Earth going to reverse polarity, that is, North becomes South...?

Answer 1

yes and apparently the effects arent very pleasant so hope it happens in the far distant future

Answer 2

Oh Brother, Capt. It's not the position of the Earth in the orbital plain that determines north and south, it's internal. Besides, what outside force is supposed to rip the atmosphere away.

To answer the question, yes. We can see the alignment of magnitized metals in the sea floor near where it spreads and see that sometimes they "point" to our current north, and sometimes they point to our current south. It seems to be a relatively instantaneous event (although it might not seem that way to humans, who have short life spans). The atmosphere wouldn't be ripped away however there is concern that the MAGNETOSPHERE which protects us from charged particles from the sun and some other radiation will be quite weak during this time. That could mean that satalites, some communications, and the health of living things is mildly affected, but not nearly to the extent that some people might have you believe (cough cough Discovery Channel). Life has made it through many switches in the past and will continue to survive many more to come. It's quite possible that the biggest effect will end up being that our compasses point backwards.

Answer 3

Yes, keep an eye on your compass!

In reality, it could take hundreds or even thousands of years. The only effect that we are likely to see in our lifetime is a possible increase in ultraviolet radiation or other ionizing radiation in random spots on the globe.

The earth's magnetic field is caused by liquid currents in the earth's core. The earth's core is assumed to be composed of molten ferromagnetic metal. These currents create a magnetic field; The magnetic field causes the current. It is a complex feedback mechanism that is hard to predict. We know that this system is currently unstable and is apparently in the early stages of a magnetic pole reversal.

If you watched a pole reversal from Mars, you would see nothing. Magnetic fields are invisible.

I disagree with some previous posts. True north and south are determined by the earth's axis of rotation not the ecliptic. This axis moves very slowly in relation to the ecliptic. This will not change. (the energy required to change it would be enormous!)

Previous pole reversals have been associated with mass extinctions. Some micro organisms are able to detect magnetic fields. If billions of them became confused all at once, it could be bad for life on earth. (That's just a wild theory, though)

Answer 4

Let me clarify this for you. The Earth's magnetic poles have been shifting. If you look at maps of polar north over the years, you can clearly see shifts. This issue was brought to the nonscientific community via north pole expeditions. They found that by using GPS systems, the former expeditions' markers were in the wrong spot. The Earth's magnetic poles are cause by its solid inner core which spins inside the surrounding liquid outer core. This core is made mostly of iron. And yes the poles will reverse eventually. The real question is will we need to change their names? Sorth, Nouth?

Answer 5

Yes. Polarity will reverse. There already is evidence that its constantly moving due to the earth's molten core's chemical reaction.

I don't know if north will become south though.

Answer 6

Sorry am sorta in a hurry and didnt examine by using all of Gentelmens remark, yet i searched fro Radiation and did no longer locate something. One cool element approximately our earth's magnetic field???? Its a barrier against the photograph voltaic radiation from the solar. because of the fact the sphere slowly starts off to shift polarity, it is going to advance weaker and in some unspecified time interior the destiny, it extremely is a split 2nd or greater time, there will be no field in any respect or at ultimate an exceptionally susceptible field. in this time we are able to be uncovered to bigger radiation blasts from the solar. regularly no longer a brilliant deal, yet shall we seem at worst case circumstances....photograph voltaic hurricane and reversal of the earths polarity on the comparable time=death??? possibly yet maximum cancers is a given. this could be an exceptionally apocalyptic view, inspite of the undeniable fact that it extremely is a a hazard one.

Answer 7

Yes but not for a long long while. And what most people don't think about is that its already happening the 23 degree tilt is part of it. Thats why theres a magnetic north and a "north north". I can't wait till north is east that'll mess things up pretty bad.

Answer 8

Yes, there is ample evidence that the world has reversed polls before and it's probably going to happen again.

The theory is, when the world changes poles, the whole world rotates 180º on it's axis and, when that happens, it's so violent that the earth's atmosphere is ripped away so everything on earth dies.

Answer 9

Previous responders are correct, and (with the possible exception of an increase in surface radiation levels due to reduced blockage of solar winds by the magnetic field) nothing much is likely to happen. The geographic poles are not about to change, except trivially due to re-distribution of earth's mass due to plate tectonics.

Answer 10

Yes, it is..
It has done so many times in the past billions of years..
The poles are already starting to magnetically weaken so
change is on the way..
Probably not for thousands of years but soon in geologic terms.
What will happen ?
Probably nothing much...

Answer 11

Yes, the magnetic poles will flip eventually. They have before and will again.
