Many of you mod the car by putting the magnet at fuel line. After that it can fly? WTF. Fuel is neutral molecules. - hydrocarbons. The majority of hydrocarbon inside a fuel is called Alkanes with formula of molecule CnH2n+2. What is a molecule? It is just a STABLE and NON POLARIZED, NON FERRIC combination of atoms. Hence, it will not be affected by electric field nor magnetic fields. Its like water. You put magnet on water can make water into what? Nothing. Exactly. Ok. Go ahead and pasang 100 magnets to your fuel line. It will fly.
