<p>During a pole reversal earths magnetic field is weak so our planet is less protected from cosmic radiation and from the solar wind.</p>

<p>How long does it take the magnetic field to move once the poles start to flip?
What environmentally would change? Does the core of the Earth flip?</p>
<p>The magnetic poles are moving now. When will it start to move faster and how would a compass behave?</p>

@trondhansen these comments do make a good answer. Is there any proof that is how it works?

The magnetic poles are moving now. When will it start to move faster and how would a compass behave?

First of all I will try to explain what a geomagnetic pole reversal is.

A magnetic pole reversal happens when the magnetic field weakens until it can no longer sustain itself. This can take 1000-3000 Years or more to complete the time it takes is very variable.

After years with a weak and sometimes variable magnetic field. The magnetic field re emerges in its original, or in a changed direction. So it is not the poles moving over the surface of earth.

During a pole reversal earths magnetic field is weak so our planet is less protected from cosmic radiation and from the solar wind.
