Earth's Poles Are Swapping Places

So you'd think this shield is permanent, right? But is it always the same?

The surprising answer is nope. Earth's magnetic field is actually changing all the

time. This is called a geomagnetic reversal, where the north and south poles

literally just swap places. But don't worry, it's not a freak event.

It's a natural cycle that's happened many times. So our magnetic field is a crucial

and super dynamic part of our planet's defenses. This invisible guardian of ours is always

changing. Makes you wonder, "What's next?"
