i remember 20 years ago i had a neon tube for my pc...but insted of neon light it had a lightning held in it like this did ...im so mad it broke i want them again
TV flybacks almost always have internal diodes inside the potted housing, since DC is necessary for CRT anode power supplies. Unless you have proven by experiment that there is no diode rectifying the output, you should assume it is a pulsed DC output - not AC. That would explain the behavior with the magnet.
Great to read your comment! I am lucky to have a very old flyback without internal diodes. I used it for Kirlian photography last year. There is a clip in youtube. AC goes capacittively through glass. The modern flybacks contain voltage multiplyer inside epoxy and give DC out. Last year I used hot air to soften epoxy and get the multiplyer diodes out making a lot of nasty smoke from burning epoxy.
Aliexpress electroschocker module gives DC out. I can try to swap + and - and see if the plasma streamer sticks to opposite side of glass tube without changing the position of the magnet
Thank you for this discussion. Looks like found an explanation. The output from flyback is not symmetric as mine a is one transistor generator. It is not sine output, but pulsed and voltage of opposite polarities is not the same. I should check with an oscilloscope
