ELI5 - Why are the rings of Saturn, which are presumably just floating Rocks, perfectly lined up in a huge ring instead of crashing into the planet due to gravity?

I think it will be something with magnetic fields but I'm Not sure.

Because they are in orbit. They are falling 'towards' the planet, but also moving sideways. They are moving sideways fast enough that they 'miss' perpetually.  Similar to how the moon, ISS, and satellites are all not crashing into the planet. 

They are in freefall, but their lateral motion is such that they never hit the ground.
