Ed Gray's Circuit, am I in this alone?

"Tesla used an electromagnet with metal tips going near the spark gap and he would turn on the magnet just as the spark appeared to QUENCH it IN THE GAP."

Well this is next to impossible, because you can never time the electro magnet correct, because of the randomness of the spark. Plus the steel is not fast enough magnetizable by far. Too high frequency for normal steel. So the electro magnet was ?full on? all the time. Nowadays it can probably be replaced by neodymium magnets.

So, the magnets WERE on the whole time?

I don't see another way... Pulsing the electro magnets on the exact precise moment as the spark almost crossed the gap just is not doable with slow steel. Steel simply is not instantly fully magnetized, and a spark speed of ultra mega short duration and frequency just can?t be reached with steel (probably non other material as well) And I don't think that materials like metglass were used ^_^ hell, using laminates was a luxury back then. And because they only had hard steel magnets in those day's they had to use electro magnets to create strong magnetic fields. So maybe today neodymium magnets can do the trick. Don't know what field strength is required though. Keep also in mind that the "tips" of the magnets, close to the spark gap need to be insulated with something like mica, which has good insulating properties and is greatly heat resistant. And can be shaped. If not used, the spark might jump to the magnet.. If not used, the spark might jump to the magnet.

currently i am working on building a tesla coil and i was wondering if when it was up and running, if the circuit could somehow be used in part of the gray schmatic... mabey im wrong and the only thing they have in common is the quenched spark gap and high voltage.Evan

I mean no offense but i don't think the gray device is do-able, I think it works and you could drive a car on next to no energy-- but the arc gap would screw up every wire-less network,cell phones and radio stations for miles.That's probably why they shut him down, in this day and age of infomation that kind of RF interference would not be tolerated, unless you could shield it for zero interference.
just a thought
