Obviously somebody wasn't paying attention in high school science class :-) In fact, the floor is full of electricity - as is everything else. Remember those pictures of atoms with electrons flying around the nucleus? So what happens (simplisticly) when you slide your feet across the carpet is that you scrape some of the carpet electrons off onto your feet. You're not creating anything, you're just using the energy of your moving foot (which came from food you ate, and so ultimately from the sun) to pull electrons and nucleii apart. Then they snap back together suddenly, creating a spark.
Same with magnets: a piece of iron will be attracted to the magnet and jump to it, but then it takes exactly as much energy to pull the nail away again. It's a conservative force.

I followed the instructions and when I changed the oil it was pitch black and full of carbon chunks.

Oh? And exactly what was your oil filter doing while all those chunks were floating around?
