Why don't planets crash into each other?

I'm not an astronomical genius but I think I have found a valid reason to why planets don't collide into each other. I found the reason to be true while messing around with some magnets. Anyway here it is; all planets have two magnetic poles, North and South. I observed with my magnets that if one hung from a bar, and the same pole got close enough to the hanging magnet, that the hung one would actually swing in a circular movement around the other one. I use this same observation to prove that planets can -in a way- be sandwiched in between each other due to their distance and same poles repelling each other. But if say Earth had N pole up, and Mars had S pole up, we would hav a collision that would end in Red-Home-Planet.

Ans2:

Much simpler than that: None of their orbits cross except for Pluto's and Neptune's. What keeps them from crashing into each other is nothing more than the very low probabliliy that they'd both be in the same place at the same time.

Oh, and since Pluto has been down-graded to a planetoid, it is no longer considered to be a planet.
