We know that by static inductance, when you rub two of the right materials together, one becomes negatively charged, and the other positively charged. Let's take one and get a neutrally charged material next to it, bringing it closer, we can see that it becomes polarized.
I've read that earth's surface is negatively charged, -500,000 coulombs, to be sure. So bringing a neutrally charged object close to it would make it polarized, is what I think is logical.
So why is my conclusion wrong, if it is wrong (doesn't seem right)? And why is it that earth is charged negatively?
