Quadpolar Tesla Coil Tests

4 Pancake Coils - 48" long!

2 Bipolar Coils - primaries in antiparellel.

1st and 4th coils have same polarity; 2nd and 2rd coils have same polarity.
2nd and 3rd coils grounded.  2nd and 3rd innermost secondaries connected

Tripolar Tesla Coil - 1st and 3rd Coils have the same polarity, middle coil has the opposing pole.

On taking a discharge from either pole to the centre, the end pole of the same polarity bursts into a brush discharge.
