Hi All

Dadhav has showed a video that we can all benefit from. Different coil and different cores. For you AC coils guys he does show a big spikes that core coils don't have, About 15 minutes in and bring corn.

Hi 49er. Very nice video. Its something everyone should see. I like how he plays down what is happening and what it means.

Hi fan

That is why I get 300 MA more draw from my style coil than a round coil. It gets a lot bigger spikes makes it draw more amps and we see a greater charge and still no noise. May be we should call it a bow tie coil instead of a 49er style... LOL LOL LOL The video does show a greater spike and your right he just blew right past that and just went on not surprised what he found.

John has always had great vidio's to share-and he hasnt let us down with this one.A steel and copper coil sounds like it may be in order.A double pulse out at 180 deg out of phase from a single pulse in-what a setup for an ssg.

Kind of stepping out of my comfort zone for intelligence here... LOL (typical) but.. it almost seems that when you wind the bowtie, you expend less energy creating an electromagnetic, and more shuttling of energy is taking place. Is that steel wire he uses, a type of enamel covered magnet wire? It would seem that (maybe) it builds it's own magnetic field independant of the core given it is a magnetic metal itself? Very cool video indeed.

Funny, I was curious about the same thing!
Coated or non...

Very educational video.
Thanks for sharing.

Hi All

The iron wire is just garden twist wire and like he said it doesn't work well.

I just tried a little experiment with some of that. Just a garden wire bifilar. It didn't seem to work well. Although I realize ammeters in and out lie, I never got any better than 40% out vs. in, so comparitively it seems poor. The spikes were not high, either, mind you my coil did not have enough turns to begin with, probably only around 100. Usually when I added a ferrite core to my copper coil I don't notice an improvement whereas with this iron wire coil, it did help.

Hi kc

IMHO the iron wire is now part of the core and it turns on and off with the transistor for a while but will become magnetized in the future.
