Does the earth's inner core stop rotating?

I'm not positive on this, but I think that it would probably not be a good thing if it did. Let's hope we never have to find out, didn't you see the movie Core? Because if you did, I'm truely sorry, if you didn't save yourself the time and money, really.

The centre of the earth is called CORE. Earth is like a big magnet as close u go to the magnet the magnetic power increases. So at the centre of the earth the gravity is maximum.\n\nSimple if we go up the gravity decreases and it inreases as we go down.\n\n\nNeo

The Earth is continually rotating on its axis.\n\nIn short, the Earth rotates because it has to in order to help conserve angular momentum in the universe.\n\nThere is a physical Law which states that angular momentum must always be conserved.\n\nThe big ball of gas and debris which out solar system was formed from had some value for its angular momentum (even if that value was zero).  When the sun and the planets formed from that material, in order to conserve the angular momentum, the planets and sun started rotating.  If you add up all the angular momentum there is now between all the planets/the sun, moons/.... it should come out to be the same value as the angular momentum of the material which formed out solar system.

The laws of physics say that an object in motoin will remain in motion unless acted upon by an outside force.  It's hard to conceive of anything that would make Earth's core stop spinning short of some planet destroying catastrophe.

The inner core is a solid and the outer core is liquid.  Although the inner is hotter, the pressure is much more intense.  This keeps it a solid because melting temperature goes up with pressure.  Since the outer core is under less pressure it is assumed to be in a liquid state.  This information has been attained by doing geophysical surveys.  Based on the speed at which waves pass through these substances, a density and composition can be inferred.

none, because the center of the earth is approximately 3000 to 5000 degrees celsius.

There is no way to measure the temperature at the Earth's core directly. near the surface of the Earth, the temperature increases by about 1 degree Fahrenheit for every 60 feet in depth............The interior of the Earth reaches temperatures of 5650 ± 600

Well, technically, it is the Earth's Core.  But if you're referring to MAN-MADE magnets, you are typically looking at superconducting magnets.\n\nRight now, it seems like the two contenders are superconductors at MIT and in Japan.\n\n\nThis may be the next contender:\n\nhttp://www.research.fsu.edu/researchr/springsummer99/departments/abstracts/BiggestMagnet.html

The motion within the "liquid" outer core and mantle, would probably impart their motion onto the solid iner core

if it stops rotating, then immediately the atmosphere will collapse, we will either feel very heavy or get stuck to the ground. this is cause the earth's gravitational force is not compensated by the centrifugal force.then there is the problem of having the same time ( day or night).the persons who r exposed to the sun will die of heat while the persons on the opposite side will die of cold.\n     if it stops revolving, then we won't have our regular seasons, if u last that long).the earth will collapse into the sun, cause the earth's attraction towards the sun due to the sun's gravitational pull is not compensated by the centrifugal force developed due to the earth's revolution. many of us cant see tv or other satellite programs, etc and etc.

the earth has a molten metallic core that's spinning...creates an em field

Yes, it does, but by a very negligible amount.\n\nDue to the law of conservation of angular momentum, the Earth has some over all value for its angular momentum (and for that matter, so does the solar system and our entire galaxy, ... as well).  As thr plane is flying around the Earth, it has some angular momentum too, different from its original value just sitting still on the surface.  In order for the overall angular momentum of the Earth to remain constant, the Earth's rotation is effected ever so slightly.\nHowever, the effect is so small, it is not even noticible when we are talking about objects as miniscule as an air plane compared to the Earth.\nAlso, since, over all, on average, for every plane flying one way, there is another plane flying the other way (or when the plane returns), so the effects are all canceled out.\n\nIt is the same principle at work is your on a merry-go-round and you move closer in to the center or farther away (or in this case, around while spinning on the merry go round), angular momentum needs to be conserved, it is the law.

Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.\n\nIf the Earth's rotation slowed down gradually over millions of years, and this is the most likely scenario, it would be a very different story. If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.\n\nBut what if the Earth stopped rotating completely? In that case, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.

The earth's magnetism is a result of the fact that the core of the earth is liquid; as the earth spins around this liquid center, it creates polarity.

The core generates heat from the long-lived radioactive isotopes in it.  At the temperature gradient which would be big enough to carry it all away by conduction, most of the mantle would be above its melting point.  So as the heat built up in the early part of the Earth's history, the mantle softened and began to convect.  We now have a stable temperature profile from the core to the crust, and a stable balance between conduction and convection to carry away all the heat exactly as fast as it is generated.

None of us would have to worry about what we going to do the next day because we would all be dead.\n\nWhat would happen if the Earth stopped spinning?\nThe probability for such an event is practically zero in the next few billion years. If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere. \n\nIf the process happened gradually over billions of years, the situation would be very different, and it is this possibility which is the most likely as the constant torquing of the Sun and Moon upon the Earth finally reaches it's conclusion. If the rotation period slowed to 1 rotation every 365 days a condition called 'sun synchronous', every spot in the Earth would have permanent daytime or nighttime all year long. This is similar to the situation on the Moon where for 2 weeks the front-side is illuminated by the Sun, and for 2 weeks the back side is illuminated. This situation for the Earth is not the condition of 'stopped' rotation, but it is as close as the laws of physics will let the Earth get. \n\n \n\nIf it stopped spinning completely...not even once every 365 days, you would get 1/2 year daylight and 1/2 year nightime. During daytime for 6 months, the surface temperature would depend on your latitude, being far hotter that it is now at the equator than at the poles where the light rays are more slanted and heating efficiency is lower. This long-term temperature gradient would alter the atmospheric wind circulation pattern so that the air would move from the equator to the poles rather than in wind systems parallel to the equator like they are now. The yearly change in the Sun's position in the sky would now be just its seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt. As you moved along constant lines of Earth latitude, you would see the elevation of the Sun increase or decrease in the sky just as we now see the elevation of the Sun change from a single point on the Earth due to the Earth's daily rotation. \n\nFor example, if you were at a latitude of +24 degrees North in the Summer and at a longitude where the Sun was exactly overhead, it would slide gradually to the horizon as Fall approached, but since the Sun has moved 90 degrees in its orbit, it would now be due west. Then as we approach Winter, you would now be located on the dark side of the Earth, and would have to travel in longitude to a location 180 degrees around the Earth to see the Sun 1/2 way up the sky because in the Winter, the Sun is 48 degrees south of its summer location in the sky. It's a little confusing, but if you use a globe of the Earth and orient it the right way, you can see how all this works out. \n\nAs for other effects, presumably the magnetic field of the Earth is generated by a dynamo effect that involves its rotation. If the Earth stopped rotating, it's magnetic field would no longer be regenerated and it would decay away to some low, residual value due to the very small component which is 'fossilized' in its iron-rich rocks. There would be no more 'northern lights' and the Van Allen radiation belts would probably vanish, as would our protection from cosmic rays and other high-energy particles. This is a significant biohazard.

Stars and planets form as a result of the gravitational collapse of accreting material. Any net translational motion of that initial material is accelerated as its radius of rotation decreases. This is due to the same conservation of angular momentum principle that makes skaters and divers spin more rapidly when they bring their arms closer to their bodies. In its extreme, this effect can make collapsed neutron starts spin many times each second, creating the regular beat of pulsars as observed from Earth. \n\nOnce an initial spin was established for the Earth, the same conservation principle says that its angular momentum will continue unless it can be transferred to another object. With no significant frictional forces to allow that to happen, the Earth can continue to spin indefinitely without any further prodding.\n\nColliding with Mars? I don't think so!!!!!
