Remember,output current of your transformer is a major factor in determining
how far out a Jacob's Ladder arc can stretch. A 15,000 volt NST with a current
of 60mA will start the arc out at about 3/4" and can stretch out to as much as
4-5", but a MOT with a voltage of only 1000-2000 volts but a current of
400-500mA will start an arc at only about 1/4" but can stretch out to 6-10". If
your 6500v transformer is of low output current (less than 5-10mA), then it
won't make a very good Jacob's Ladder.

Hi,

6500v ought to be enough for a small JL. The reason the arc climbs is that
when the arc jumps accross the bottom, it creates ionized air. Ionized air
is a decent conductor, and since it is warm, it rises. The arc follows it up
the ladder, as it is the lowest resitance path.
