Gant Posted July 22, 2004 Share Posted July 22, 2004 Is there a differance between the geomagnetic field of the Earth,and the magnetic field of a magnet? And how far does the Earth's geomagnetic field reach into space? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted July 22, 2004 Share Posted July 22, 2004 There isn't much difference, except Earth's is bigger. Link to comment Share on other sites More sharing options...
[Tycho?] Posted July 22, 2004 Share Posted July 22, 2004 A magnetic field is infinite in extent, so it reaches out forever. Link to comment Share on other sites More sharing options...
LucidDreamer Posted July 22, 2004 Share Posted July 22, 2004 I think tycho is right and that magnetic fields created by electromagnetic forces is like all other forces and it has infinite reach. But like gravity, the effects of a magnetic field become smaller and smaller as you get farther away until its pretty much inconsequential.

Gant Posted July 22, 2004 Author Share Posted July 22, 2004 hmmm,,,then the magnetic field becomes unmeasureable after a certain distance? Link to comment Share on other sites More sharing options...
LucidDreamer Posted July 22, 2004 Share Posted July 22, 2004 I think that at some point if we headed out into space we would be unable to measure earth's magnetic field with current instrumentation. Link to comment Share on other sites More sharing options...
Sayonara Posted July 22, 2004 Share Posted July 22, 2004 With more sensitive equipment you'd be able to detect it further away, but I imagine there would come a point where it was indistinguishable from other fields. Link to comment Share on other sites More sharing options...
Gant Posted July 23, 2004 Author Share Posted July 23, 2004 Then,,,lemme go out on a limb,,,if the earths geomagnetic field is no different than a magnets magnetic field,,,then it is theoretically possible to generate a magnetic field on a probe to help push itself away from the Earth,,or is this a TOTALLY different type of field? I think i hear that limb breaking,,lol Link to comment Share on other sites More sharing options...
ydoaPs Posted July 24, 2004 Share Posted July 24, 2004 are you talking about superconductors for levetation or deflection of said probe? Link to comment Share on other sites More sharing options...
Gant Posted July 24, 2004 Author Share Posted July 24, 2004 mmmm,yes Link to comment Share on other sites More sharing options...
tecvia Posted February 25, 2011 Share Posted February 25, 2011 Earth's magnetic field is confused, w/ very poor alignement and fluid [no pun intended] in vector and amplitude. Magnetic waves come from aligned electron movement [orbital or atom to atom flow], no matter the source. Once emitted it should be infinite. To the propulsion question, at the north magnetic pole would a magnetic "north down" pole weight be lighter than in the "south down position? How much? Field strength and distance?
