Can We Create a Magnetic Field on Mars through Moon Formation?

[Sei]

Hi guys,
I'm new to this online stuff, but after reading what you all have said, you've forgot one step. Why is it that we have such a high magnetic field and Mars doesn't. Its all about our beginnings. We were much as Mars was in the beginning, about the same mass. Then our sister planet hit us. The Iron and nickel that was in that planet joined with ours and the lighter materials (planet crust) was flung into orbit to produce our moon. The combination of increased mass, higher spin rotation due to collision, and the pull of the moon to slow our rotation made or magnetic field and saved us from the fate of Mars. I'm starting a paper on the possibilities of increasing the mass of Mars core and increasing its radioactive core materials to build a sustainable magnetic field to hold a atmosphere in the future. I'll keep you all posted on what I find.

[WARNING] Bad english :P
Let's talk about Solar System's History (Theories mixed).
First, Jupiter formed and migrated inward, stripping materials need for a super-Earth's. Then it was pulled out by Saturn.
Without sufficient mass, Mars is rather a small surviving planetsimal with mass of about 1/10 Earth Mass, then it cools down.
Proto-earth during The Giant Collision is more massive than Mars is today (Theia, the sister planet you said, is Mars-sized.) The collision mixed their cores and proto-earth gained it's current density (5.514 g/cm^3).

Actually, if you want to increase a martian core mass, do this:
1. Find a nice, big iron ball. Maybe some more silicates too.
2. Smash it into Mars. This may create a new martian moon in process.
3. Heat it sufficiently until all heavier matter fell down into the core.
4. Cool the planet down.
5. Terraform the result.

This would take millions of years or even more, so I'll suggest everybody read the Lagrange Shield from Orion's Arm.

none of that explains why the Earth has a magnetic field and Mars doesn't, as asked by @kevin retired navy

The lack of a rotating solid inner core within a liquid out core is the main reason for the lack of a magnetic field on mars
Mars maybe once had a field till it's core cooled too much to be able to support continued rotation ( haven't found any info suggesting yes or no to that)Dave

all that is very highly speculative and you haven't supplied any reliable referencesD

Isn't the outer core solely affect the mangetosphere? I thought it was. Mars's core cooled down and no longer convective while Earth's core is.

it's the interaction between the inner and outer cores of the Earth that generate the magnetic field

from wiki and there are other sources --- some mention the inner core some dont

Earth's core and the geodynamo
A schematic illustrating the relationship between motion of conducting fluid, organized into rolls by the Coriolis force, and the magnetic field the motion generates.[41]
The Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of highly conductive fluids.[42] The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km). It is divided into a solid inner core, with a radius of 1220 km, and a liquid outer core.[43] The motion of the liquid in the outer core is driven by heat flow from the inner core, which is about 6,000 K (5,730 °C; 10,340 °F), to the core-mantle boundary, which is about 3,800 K (3,530 °C; 6,380 °F).[44] The pattern of flow is organized by the rotation of the Earth and the presence of the solid inner core.[45]

Oh yes, the convective outer core is due to the inner core heating it up. Sorry, I forgot.

Anyways, the real reason of Martian core not generating magnetosphere is having no outer core for the inner core to interact with?

Let's call a planet doctor to help warm this thing up.

I would conclude that the present lack of a molten outer core would be the main reason

obviously, it must have at some stage as evident by the once active volcanism on Mars

Tharsis Montes. Pretty sure it is a shield volcano.

And now we have to warm it up or shield the radiation.

and the biggest volcano so far discovered in the solar system ... Olympus Montes, dwarfs anything here on earth

Just Olympus Mons, unlike Maxwell Montes, which is many mountains.

Let's talk about warming the martian cores...?

unfortunately, since it's not possible with today's technology and it unlikely to be in the foreseeable future

it would be a highly speculative and pointless discussion

On the Physics Forums, we keep discussion as factual as possible and within the realm of known physics

cheers

It's a bit possible, if we have two planets colliding each other, which is useless, probably.

 

[Alltimegreat1]

We just have to create a liquid mantle, several thousand atomic bombs detonated deep within the crust ought to do the trick.

What about nuking Phobos and sending it crashing into Mars?

This thread has become too speculative, and will remain closed.
