What would happen if Earth suddenly changed its polarity?

Question

PS.

Iam speaking about the both.

Answer 1

You wouldn't have to worry about it.

Answer 2

Your compass would point south.  The earth's polarity has actually reversed many times during its history.  It appears to be a regular occurrence, and happens pretty suddenly.  There would probably be some kind of magnetic field turbulence for a while that would disrupt radio signals around the world.  Nobody knows what this would be like or how long it would last.

Answer 3

In that question are you asking about a geomagnetic reversal or a polar shift?

If it's a polar shift then equatorial regions would become polar and polar regions would become equatorial. However the theory is unproven and pretty unlikely without an impact.

If you're talking about a geomagnetic reversal then, if it was instantaneous, virtually nothing. A compass needle would point in the opposite direction and that's it. The magnetic field would still be there so there wouldn't be any damage caused by the solar wind.

Answer 4

Wildlife that used the magnetic poles for migration might be messed up (perhaps), but little other change.

Answer 5

we will practically study the bigbang theory

Answer 6

There would be major disruptions in many things. One of the answers above seems to have summed it up very well.
