My geology prof says that no one knows.
I think I'll cry if that's true.
It's driving me nuts.

The Earth's magnetic poles switch every once in a while because of a natural process called geomagnetic reversal. This occurs when the Earth's magnetic field, which is generated by the movement of molten iron within the Earth's core, changes direction.
The Earth's magnetic poles switch on average every 200,000 to 300,000 years. However, the timing and frequency of these reversals can vary and are not completely predictable.
The last magnetic pole reversal occurred about 780,000 years ago, so we are currently overdue for another reversal. However, it is impossible to accurately predict when the next reversal will occur.
The switching of Earth's magnetic poles does not have a direct impact on human life. However, it can affect animals that navigate using the Earth's magnetic field, such as migratory birds and sea turtles. It can also potentially affect satellite and communication systems.
Yes, the Earth's magnetic field has been weakening over the past few centuries. This is a natural process and is not cause for concern. Scientists believe that this weakening may be a sign of an upcoming magnetic pole reversal, but it is not a definite indicator.
