inquisitive Posted January 28, 2005 Share Posted January 28, 2005 Do all planets have magnetic fields? Is it a spin thing? Link to comment Share on other sites More sharing options...
Molotov Posted January 28, 2005 Share Posted January 28, 2005 No. It depends on the composition of the planet. Earth's magnetic field is generated by its solid metallic inner core rotating in the outer liquid core. I have no idea how magnetic fields are generated in stars and gas giants but i'm guessing its a similar process. Link to comment Share on other sites More sharing options...
Gant Posted February 14, 2005 Share Posted February 14, 2005 Molotov is correct,,Stars on the other hand have what is called solar loops,,pretty complicated to explain,,but the suns magnetic field is actually in its sunspots. Check out this site for more info. Its quite informative. http://www.sunblock99.org.uk/sb99/people/LFletcher/sb99_lop.html Link to comment Share on other sites More sharing options...
5614 Posted February 14, 2005 Share Posted February 14, 2005 Do all planets have magnetic fields? Is it a spin thing[/b']? the angular momentum or quantum spin of an atom can cause a magnetic field.... that is not the same as something physically spinning!

ed84c Posted February 14, 2005 Share Posted February 14, 2005 electrons have 2 spin anyway. Link to comment Share on other sites More sharing options...
YT2095 Posted February 14, 2005 Share Posted February 14, 2005 Do all planets have magnetic fields? No, they all have Gravity though (as do Moons). the magnetism comes from the composition of the bodies mass, spin only helps with alignment of magnetic domains in a liquid core, other than that, it`s either fixed or non-existant Link to comment Share on other sites More sharing options...
swansont Posted February 14, 2005 Share Posted February 14, 2005 electrons have 2 spin anyway. spin 1/2 Link to comment Share on other sites More sharing options...

YT2095 Posted February 14, 2005 Share Posted February 14, 2005 Hmmm... I read 2 as "to" in this new fangled crappy txt msg thingy, I agree, certain shortcuts in the field of science should NOT BE taken! Link to comment Share on other sites More sharing options...
YT2095 Posted February 14, 2005 Share Posted February 14, 2005 The fields change in strength and direction, so it's not fixed. you misunderstand me here. my point is that if OTHER than a liquid core of the correct magnetic material. the only other 2 options are a Solid core of the correct material and still magnetic (hence fixed) or a planet comprised of a material of a non magnetic property.

calbiterol Posted February 14, 2005 Share Posted February 14, 2005 Mars is generally considered to be a magnetically dead planet, meaning its core is solid (cooled) and it has no magnetic field, correct? Is there any way to restart this process? Maybe a detonation in the core? Hypotetically... Just wonderin'. Link to comment Share on other sites More sharing options...
YT2095 Posted February 14, 2005 Share Posted February 14, 2005 No, not really. it would take MASSIVE amounts of energy to make a "dent" in it, and by doing so, you`de create problems not yet encountered. much better to use a GPS system and take your geo coords from that Link to comment Share on other sites More sharing options...

ROFLOL swansont; you said 1/2 spin? you know more of this than i do. What has 2 spin then? For those who done know; 0 spin= Any agle is the same e.g. a circle 1/2 Spin- Same at 2 points e.g. playing card 1 spin- Same at only one point e.g. table 2 spin- Spins twice to be at the same poiint. I think. Link to comment Share on other sites More sharing options...
5614 Posted February 14, 2005 Share Posted February 14, 2005 spin 1/2 or -1/2 Link to comment Share on other sites More sharing options...
YT2095 Posted February 14, 2005 Share Posted February 14, 2005 ROFLOL................ I think. Wahey Someone at last actualy understood something oblique! I think? Link to comment Share on other sites More sharing options...
swansont Posted February 14, 2005 Share Posted February 14, 2005 or -1/2 Right. Spin 1/2 can have a projection of +1/2 or -1/2. Link to comment Share on other sites More sharing options...
