		<description>Does the media (rock/lava) in which this reversal was measured effect the results. As the rock is undergoing some serious stress at the time, both thermally and mechanically.
Maybe we don&#039;t know enough about what happens inside lava when it moves and solidifies to really understand the properties shown in these studies.
for instances can anyone link a study that has looked at lava that we know has had a steady magnetic field applied say in Yellowstone or Hawaii?</description>

		<description>well, this idea about a fast flip; Jan 2012 the sun&#039;s northern hemisphere went off all together.  About this time the N magnetic pole took a giant step forward.  Related?
I wish somebody would do up magnetism, gravity and electricity.  And why is that so hard? Since Maxwell we have got zip.  So is Miles Mathis right?  He says our system is unbalanced compared  to outside our solar system. We have committed some energy conversion that leaves us with more matter than anti matter.  Just maybe the problem is our system is a gas powered  car and we think it is an electric car?</description>

		<description>The flip may not mean much to us but what about the creatures that navigate using the planets magnetic field?</description>

		<description>It is very interesting... Rapid polar shift will switch north to south and east to west.... Then, Sun will rise from west and sink in east. Are there any observance in known history of humanity? I only read about end time prophecies of some ancient societies...</description>

		<description>So ... Shock! Horror!.. That &lt;i&gt;Core&lt;/i&gt; movie got it wrong? ;-)

@2.   Confy Says:

&lt;blockquote&gt;&lt;i&gt;Not so. They had sextants and &lt;b&gt;Polaris.&lt;/b&gt; :-) &lt;/i&gt;&lt;/blockquote&gt;

Well the northern hemisphere one&#039;s have Polaris, those in the southern hemisphere (like me) have to make do with faint little Sigma Octantis - although we can still use the Southern Cross, Canopus, Achernar etc .. as navigational markers.  ;-)

PS. Of course this changes over time with precession &lt;i&gt;(the top-like &quot;wobbling&quot; of the Earth&#039;s axial tilt)&lt;/i&gt; meaning the &quot;pole stars&quot; in both hemispheres gradually change  over  tens of thousands of years. Canopus - the second brightest star in the sky - will one day be the south pole star while the north gets to see Vega replace Polaris at some point too.</description>

		<description>I imagine that a flip would probably be a huge deal. Causing even what we might consider to be be minor changes in the oceans currents and the weather patterns on paper, could vastly change the world we live in.   We always seem to underestimate how big this laboratory is that we live in and how many systems are involved and affected (all of them).  If and when it happens I&#039;m sure it&#039;ll be a surprise and a fun ride.</description>

		<description>A magnetic pole flip isn&#039;t a big deal? What would it do to our satellites and our power grid? Isn&#039;t it possible that these findings reflect sudden damage to a collapsing magnetic field due to strong solar maximums like the one we will be experiencing in the next few years?</description>
