Homemade high voltage pulse transformer video

video Homemade high voltage pulse transformer video

I made this by winding lots of 40SWG wire around a PVC pipe and then covering it in electrical tape. I then used some 2.5mm2 house wiring cable as a primary coil and pulsed 1.2kV DC using one of those hand-held bug zappers through a spark gap and a timing capacitor of 0.047uF and the result is a high voltage spark on the output.

i thought the core must be magnetic?

The core must be ferrous, which it is. When it is used as a core it magnetises and de-magnetises each time there is current going through the primary coil.

Basically it switches between being magnetic and non-magnetic.
