Can Humanity replace Earths magnetic field?

Assume if the magnetic field where going to disappear and bring extinction that all humans would participate in attempting to replace it to keep ourselves alive. Is it even possible technology wise? Is there enough resources and technical knowledge to replace it?

How would it work? What would it look like?

No. Earth's magnetic field is a result of the constant movement of molten iron in the planet's core. We could not even come close to duplicating it artificially, nor do we have a need to, as it won't be going away any time soon.

Assume nothing, its pointless ..... lets work on facts and actuals. It's not going to happen, cant happen but i'm sure 2x type CERNS spinning in opposite directions may give ................ nothing .

Get me off this planet!

Simple answer: no.

The reason is quite simply that we don't have a spare 760 miles large, nickel-iron Earth core lying around.
And building one would require mining from the Earth Core in the first place - which would come as the same as keeping the old core there.

As "stupid" technology wise we are today, nothing human made could replace the magnetic energy the planet is making on it's own, ask again in 1.000 to 100 k years.

The magnetic field can be replaced using sound/vibration.

Besides making your compass ineffective, it would apparently have little or no effect on surface activity.

I was educated on this subject by someone here recently who pointed out that our magnetic field is not the primary protector against the solar wind and cosmic rays.

Apparently, the nitrogen in our atmosphere can absorb up to 10keV so the magnetic field's contribution has more to to do with limiting the bleeding off of our atmosphere by the solar wind which would take millions of years.

Good luck with believing that.

When was the last time your compass needle followed your voice?

They already have machines that can make O-ZONE. You can find them online anywhere. It creates a greyish blue smoke.

At is current state of social and cultural evolution no but in theory it is possible, it is also possible to tap the vast amount's of energy in the magnetosphere which would be far simpler.

The problems are how much power you would have to use to create the artificial magnetosphere and the vast amount of work that would be needed with what would amount to being the largest human construction ever.

Two varient's are possible if the human race behaved with unity and a common purpose (Something only a unifying religion or mind control could bring about and non of the current world religions fit the bill as this religion would have to be a mind controlling construct in itself).

One. a series of superconducting coils on the surface of the earth (Capacitive inductance would be a problem - when you send a direct current along any length of cable "superconducting or not" (but some form of coil's and shielding with AC alternation could be a work around) the electron's back up in in a capactive manner and this causes an inductive resistance meaning DC will not flow over vast distances (instead the length of conductor charges like a capacitor) hence we use AC which is normally no good for our purpose as we want a stable not an alternating field), the flow of vast numbers of electron's would create a magnetic field just as the friction in our earth's molton metal core does and if powerful enough this field would reach into space and form a new magnetosphere but probably not as good as our natural one.
Two. as One but in space itself perhaps using solar power to help power it in a series of vast orbital ring's.

It is possible to simulate the core but the size of the constructions would be huge, even small magnetic bottle's used in fission experiment's are hard to create and maintain in a stable fashion but never say never.

We would never do it though as our species is too fractured and independant of thought, other concerns would drain the effort even when it became an inevitability.

That said Magnetic bottle's (Artificial magnetic shield or mini magnetospheres) have been researched many time's by NASA and the Russian space agency's as potential protection's from harsh radiation for space craft and satellite's, likely the military have pursued this with more vigor though as it would help to shield against EMP and solar flares and all a magnetic bottle is, is essentially a copy of the earth's magnetosphere.

Now is the earth a Natural phenomena?.

Your assumption is wrong. It might make navigation a tad difficult, but the lack of a field would not lead to extinction--just some inconvenience.

Without the magnetosphere super high velocity solar particles would slowly deplete the upper atmosphere, sure it would take hundreds of thousands or even millions of years to be noticable and the planet would likely sustain an atmosphere regardless but this bombardment would also heat up the particles in the upper atmosphere with vast weather and global temperature implication's.

Extinction of the current forms of life is a probability, also many forms of life, insects, fish, birds and possible even some mammals are sensitive to the magnetic fields using them in there migratory pattern's so they too would likely suffere extinction, so the eco system would be shot and life would have to seriously adapt.

Life probably would survive assuming conditions mild enough for it to do so remained extant upon the surface of the earth, chemo synthetic life would also survive as well as deep crust microbes which are extremophiles.

You should be more concerned about all the chemicals in the air that disrupt the o-zone. I'm sure you already know about the area's in the ocean that have little to no protection. holes in the shield. These holes are moving along with the other holes up there. The planet is warming and the more it warms up the more it releases all that methane gas under the ice permafrost, which is highly toxic and heats up the planet very fast. You already know that some states are pushing to pipe water from the great lakes to those states in need of water. Not only that, you should already know that companies are draining the great lakes water for use around the world. How do I know. I live there. Holes in our shield is especially vulnerable to the sun. The poles are warming and the ice is melting. You ask why. My theory is that a force outside planet earth is the cause. Push this domino and all the other planets fall into chaos as it moves closer and closer to our sun.

You're right, "inconveniences" such as the absence of a magnetosphere which would allow solar particles to pass right through and reach Earth itself, leading to the sterilization by ionisation of the surface of the Earth.

Just a minor inconvenience.

Bravo, Bravo How true. Maybe we can strengthen it by spinning the earth a tad faster. Say to a 23 hr. day. He, he, he, he,

So what's the point again? I think maybe an asteroid will hit before then.

Sounds good, they also discovered, or confirmed fairly recently that the viscous part of the core travels very, very quickly compared to the delicate crust. I think the core is also offset maybe like an inertia wheel, as well as gravitational effects form all around the solar system, it's a big jelly

This may not only answer your question, but help provide the type of context you would need to even fathom your question:

Well, the magnetic field is not very strong, but it is big. Very very big.

The resources required for us to perfectly emulate such a field would be on a planetary scale. In comparison, the Great Wall of China is small, the largest dams are tiny and the LHC is vanishingly miniscule.

My 'back of the envelope' calculation estimates that the energy currently stored in the Earth's magnetic field is greater than 10+e19 Joules. This is close to the energy that would be released by about 4,000 H-Bombs of 50 Megatons in yield (the largest nuclear explosion that we have ever created). This is also nearly 6,000 times the total electrical power generated by the United States in a year. Remember that the Earth's magnetic field power is an instantaneous measure, we'd have to keep it up perpetually.

I don't think we could do it. Fortunately, we shouldn't need to. The heat that melts lava also keeps the Earth's outer Iron core molten. The inner core is solid due to pressure. Convective forces wound by Coriolis Forces of the inner core, within the outer core, cause the Geo-Dynamo which produces the magnetism.

Ozone's got nothing to do with the magnetic field of the Earth.

eta: by the way, that's ozone. Not o-zone. There's no hyphen, the etymology of ozone doesn't include the word 'zone'.
