Ultimately, what the film comes down to is this:
At some point, a massive asteroid hit Earth. This asteroid, supposedly, was loaded with such an incredible amount of magnetic material that it's capable of attracting other bits of space rock that are equally magnetic; if something gets into the atmosphere while in that area, it'll pull it in. This leads to even more magnetic material being in that one spot, which leads to even more things getting pulled in.
The critters in the film decide that the best way to get rid of the incoming extinction-level-event hunk of rock is to use a volcano to shoot all of the magnetic material they can find up into the sky, in the belief that it'll cause the hunk of space rock to be pulled up into space with it.
Given that this is at the heart of everything, I'm just going to simply put the concept itself here rather than any specific questions.

Given that this is at the heart of everything, I'm just going to simply put the concept itself here rather than any specific questions. to make sure I understand this; you are saying there is an accumulation of magnetic material on the surface, and there is an extinction class nickel iron meteor incoming? the plan is to shoot the magnetic material into space to magnetically deflect the meteor? this would seem to relate to the deflecting a bullet with a magnet concept. I'm sure a physics (dare I say?) "wonk" could develop a model for how close the magnetic mass would have to be and what the releative speeds would have to be to get a desired amount of deflection. all i can say is they would probably have better luck actually HITTING the meteor. but I'd love to see the conclusions. |

Yep. They even got Neil DeGrasse Tyson to appear in a cameo as a scientist to present the concept. That's not the only thing in the film, but it's the big one. Other things in the film: 1. Critters living inside the remains of one of the previous big ones are, in fact, "elderly", if not several hundred years old, but are still in the prime of their lives because something about the magnetic nature of the crystalline structures within retards aging. Once the remains are destroyed in an accident, they begin to revert to what their real ages should be. 2. The Fountain of Youth is nothing more than a deposit of this magnetic crystal material inside a body of water. 3. Scrat is the reason why there's no life on Mars; he crashed the UFO onto the surface with such extreme force that it was akin to an extinction-level-event meteor. |

Scrat is totally plausible. that little guy just has the WORST luck.

Scrats UFO would also have to be a time machine, current theories suggest Mars would have lost its atmosphere and water around 3-4 Billion years ago. There are many areas of the Earth that have local magnetic anomalies, the area in Canada where a lot of mining goes ahead is one of them i forget it's name it was caused by large metallic meteor colliding with the Earth. I do not know of any altered ageing process there. :  |

Magnetic forces follow the inverse square law. As such a magnetic field strong enough to pull something from orbit that wasn't already going to hit...Well meteors would be the least of your problems. I'd be more concerned about what such a field would do to the iron in my blood...or I would be if my nervous system hadn't basically shut down when I got within 1000 miles of it.

Him got a point there.... If you lived on a planet that was mostly "Rare earth" neodymium type magnets, would your bloods contain FE type combinations?... probably not if you want to be anything but a flat blob?... A "Big magnet" in the cosmos would create an extra slice of a heavy gravity plus more forces type situation and would attract anything ferrous, thus accelerating its own magnetic plus gravity field. "They say" that as the earth's "core" if almost molten iron, maybe thats what caused this planet to start being something more than just a rock?. Maybe it needed that boost of magnetic attraction to start collecting enough to be a proper planet in the first place, and as soon as it got big enough to have a gravitational significance, other non magnetic matter got attracted to create the planet. However, all this can be no more than speculation as none of us, even me the current form of an ancient immortal dragon, where there when this solar system formed.  ... But I doubt Iron in the blood would be good on a massive magnetic rock. This does raise a question... The outer mantle of earth is generally not that magnetic. How far could you dig down into the earths core, if you could, before the magnetic forces down there began to give you problems such as described... |

Also, this raise a question.
In one of the episodes of "Eureka", the character "Fargo" was described as anaemic and in need of extra iron supplements.
During an incident of massive magnetic fields being created, he was thrown towards the ceiling.... [or anywhere this field was created]
Now I myself have to go through a massive magnetic field at the end of the month... MRI scan...
How big and powerful would a magnetic field have to be to make problems big enough to affect the Iron in someone's blood?... and would being on Iron supplements be a significant factor in being an extra problem?..

Copper is an alternative to iron as the binding element in blood - yes, Star Trek actually got that bit of biochemistry right. So on an iron poor world copper would be a viable alternative.
The amount of iron you'd need in your blood for any magnetic field you are likely to come into contact with to affect it would be lethal on its own. Any field strong enough to affect none lethal levels of iron in the human body would most likely screw up the nervous system long before it affected the blood itself. The human nervous system does, after all, basically work by the flow of positive and negatively charged ions.
The earths magnetic field is created by a liquid iron core that is rotating rapidly. As to how far down you could dig down before it affected you...Well the crust is between 3 and 30 miles thick and after that its molten rock. So magnetic fields would be a rather minor issue rather quickly. Even if you could deal with that the gravity would probably cause more problems than the magnetic field.
Unless of course you happen to be part pigeon, in which case magnetic fields are how you navigate. I would imagine a pigeon in an MRI scanner or close to one would not be a happy little bird.

I wonder if it would cause some corollary to seasickness. |
