Magnetic field reversals aren't a regular event, or rather they don't occur in any known predictable cycles.
It will get weak and moreover spotty, with pockets of north field in Southern Hemisphere and visa versa. Eventually the North magnetic field in the
Southern Hemisphere will strengthen and stableize. The Northern Hemisphere will become magnetically south.
The northern hemisphere actually is
a magnetic south field. Thats why the north of a compass points to it.
This will take about a 1000 years.
There's been lots of different estimates as to when it will happen, what research are you using?
Keep lots of sunblock, hats and UV sunglasses around.
I'm not quite so certain that there'll be a complete loss of field strength all around the planet, and I don't think that UV radiation is deflected
by the mag field anyway, its ionized particles that are defelected by it no?
Who cares how many times its been talked about
I think the previous poster was just saying that perhaps, if nothing new is being brought up, then why start a new thread?
