I read recently on cnn.com that the sun's magnetic poles have reversed as part of its normal 11-year solar maxium cycle. Why does this happen? How does it happen? What effect does it have on the sun? I also read that the earth's magnetic poles reverses from time to time, but with less predictability, the last one occuring around 800,000 years ago. Why is the earth's behavior less scheduled? What effect would the reversal of the magnetic poles have on earth's ecology, and humans' technology? I'm not a science major, but I do have a strong interest in all fields of study. Thank you for your time. :)
