BPHgravity Posted May 30, 2004 Share Posted May 30, 2004 Is it possible for the Earth's magnetic field reverse in polarity? I have recently read an article that suggested the Nothern Aurora is getting weaker due to a change in the flow of molten magnetic material in the center of the Earth. This in effect will flip the magnetic poles. It also suggested the Earth's magnetic field may have reversed several times in its history. I've never heard of this.

Z-space Posted May 30, 2004 Share Posted May 30, 2004 The magnetic field also shifts because of wobbling of the planet on its axis during its rotation about the sun. Link to comment Share on other sites More sharing options...

aommaster Posted May 31, 2004 Share Posted May 31, 2004 Yeah, I heard that it reverses polarity too. I think it was once in 26,000 years or something! Link to comment Share on other sites More sharing options...
