Teddy, Wayyyyyyyy back at Purdue in the late sixties we used what was called the "Righ Hand Screw Rule" which it appears is what the good Bus Drivers article explains better n I ever could..... Of course, manetism and electricity are well related, and the magnetic fields North/South Magnetic Polarity is what determines the resultant induced voltage, resultant current flow and Electrical Polarity. Thats why a generator needs to be Polarized in the corect North/South Magnetic Polarity so once the armature (coil of wire) spins inside it the correct corresponding Electrical Polarity is achieved so current flows into n charges the battery
Great question, has to be a short answer here cuz it takes books to explain it completely

To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
