Pole reversal or geomagnetic reversal. The North and South pole "flip", in the case of the earth, the magnetic North pole (normally at the top of the earth), would now be at the bottom and the magnetic South would be at the top.
This has happened hundreds of times over the history of the earth and can be "read" from the orientation of magnetic crystals laid down in molten igneous rocks which "record" the direction of magnetic North as the rock cools.
Should such an event happen during our lifetime the effects would be substantial, but not life threatening. Compasses would be reversed, GPS systems would be out etc. But all of these things can be rectified with some smart programming, re-labeling and re-orientating ourselves to a new way of life.
Sadly, this may not be the case with animals; many animals, mammals, insects and fish use the Earth's magnetic fields to orientate themselves for location and navigation. If a polar flip were to occur, we may find pods of dolphins or whales becoming beached, flocks of birds loosing their way during migration. This could result in large number of these animals dying before they were able to "re-calibrate" themselves.
Maps and geographical reference would have to be changed. For example you couldn't call the "Middle East" that any more as it would now be the "Middle West". The West Wing of the White House, would now be the East Wing etc :)
Think about how things would change if such a reversal were to take place, what things would be influenced and how that may affect your daily life.

How often is there a polar reversal?
Polar reversal, or geomagnetic reversal, happens on average every 450,000 years, though the range of time varies widely.There is a link to an article on geomagnetic reversal below.
Do the earth's magnetic poles have reversed themselves?
Yes, in the history of Earth, it has happened a handful of times. When it switches we experience what we call a pole reversal. Right now Earth is currently in the process of a pole reversal (the South Pole is moving northwards).
What is the evidence of pole reversal?
The evidence for Earth's magnetic pole reversals comes from the Geological record. If you look at the fossil polarity of a section of sea floor taken across and to either side of a mid oceanic ridge, there is a mirror pattern of stripes where the rocks have reversed polar directions. Similarly the poles of the Sun reverse every 11 years as the sun goes through a maxima and minima.
A pole reversal is when Earth's?
magnetic field flips its polarity, so that the magnetic north and south poles switch places. This process is natural and has happened many times throughout Earth's history. Reverse pole fluctuations have occurred roughly every 200,000 to 300,000 years.

What happens to the magnetic orientation of rocks as the poles reverse?
During a magnetic pole reversal, the magnetic orientation of rocks changes to align with the new orientation of the Earth's magnetic field. This means that the magnetization of rocks will also reverse during a geomagnetic field reversal event.

The sun's pole reversals are tied to its?
The sun's pole reversal is tied to the sunspot cycle.
The most logical interpretation of apparent polar wandering is?
the north pole (or south poled during periods of magnetic reversal) has remained fixed and the continents have moved in relation to the pole. Page 90 Chapter Three
When was the last known magnetic pole reversal?
Roughly 750,000 years ago.

The switch in direction of earth's magnetic north and south poles?
The switch in direction of Earth's magnetic north and south poles, known as geomagnetic reversal, is a natural phenomenon that has occurred several times in Earth's history. During a reversal, the magnetic field weakens and flips in polarity, causing the north magnetic pole to move towards the geographic south pole and vice versa. These reversals are a normal part of the planet's geologic processes and do not happen on a regular or predictable schedule.
