What will happen when the magnetic field is gone? what well the earth look like? Won't anstroinds and other gases hit the earth and we will just be another planet with no life?
But they are saying the magnetic field will come back but I don't get what happened once it did lose its magentic preasure.

I don't think you need to worry about the Earth losing it's magnetic field anytime soon...! I think that it's a cycle.. the poles will just be reversed. I don't think that all life will be exterminated when that happens. It'll probably mess up a couple of satelites and electronics but our day to day lives won't be changed much I think. Anyway, whenever it happens, we'll be lonnnnnnng gone!!

OK, here goes. Earth's magnetic field is supposed to be due to the action of a dynamo mechanism at the centre of the earth. So as long as the dynamo works there there is no chance of magnetic field being turned off. The magnetic field can change its direction.North becoming south and south pole becoming north pole. It has happened and will keep on happening. This has to do with the dynamo mechanism (poloidal fields becoming toloidal field and stuff like that)
Earth's magnetic field is very weak (Horizontal magnetic field intensity ~10^(-5)T). Hence there is no chance of it preventing asteroids or huge meteoroids from hitting the earth. It can restrict the amount of charged particles (mainly from the sun) striking the earth's surface (except at the poles) and can give rise to auroras.

the earths magnetic fields are the earths protection from the ionic rays comming from the sun. if the magnetic fields are disperesed then the ionic rays will start bombarding us and we could end up dead or mutated. the magnetic fields at the earths poles are very close to the ground thats why we see aurora borealis or aurora australis near them. the auroras are actually ionic rays that are close enough tot he earths surface.

look how mars is that what will happen when there is no magentic field. that is the reason why mars looks the way it does today
