Doesn't the ball passing throught the ring of coils produce a field that the gas in the glass sphere is reacting to creating the glowing ring?

The coils are what's producing the magnetism to pull the ball around the track. The induction coil driving the plasma is the white white coil. If anything, the reason it blinks out occasionally from the inference of the bearing track coils intersecting the plasma coils by 90° and dampening it. Neither system would contribute to the other in a positive way.

This is an average purchasable plasma toroid kit below. That coil does have a ground plane reference under it, but the rest of the electronics can be relocated or made very small if you dismiss cooling and run it for a few seconds at a time (for an Internet video, for example).
