Tesla's "COIL FOR ELECTRO-MAGNETS".

[Magluvin]

My first serial bifilar was shop wound, 800 turns, filled with welding rods. I was testing it's magnetic strength running dc current through it with a 12 volt battery, then suddenly a shock went through the coil and when re-connected, it pulled a cutlery case all the way across the kitchen counter, scaring me. I don't need to read any text material from you to help me understand my experience.


Try and impulse charge the serial pancake with high voltage, then retest it and see if it makes a difference.

First, are you saying that you put the 12v batt across the coil, is that put on as continuous dc, or just pulsing it?
Second, when did the 'shock' happen? When the batt was pulsed to the coil or mid dc current?

Third, what makes the coil different after the 'shock'? Is it that the core has become magnetized, or are you saying the coil capacitance is charged?  Unless both ends of the coil are open, there is no charge in the coils cap when series connected with open ends and no input.

The pulse apparently magnetized the welding rod core. The magnetizing force of the coil multiplied tremendously! Conradelektro should try and pulse magnetize the steel plate while he has the experiment set up. This is similar to the PMH effect. I want them to awaken to the superior magnetizing power that's latent in that serial bifilar pancake coil!

Pulse with what?

It looks like pretty thick wire. I would try a 12 volt car battery. These coils start to exhibit special qualities when activated with hi-voltage pulse. I want him to try to pulse the coil over the steel plate and see if the plate acts like a magnet.

...  you're changing your mind now and maintaining that Itsu's running at 2250 RPM and quoting me as wrong, when you stated that his RPM was 9,000!

synchro01:

Yes, that is why I wrote (in the 2nd paragrph) that WE ALL make mistakes! (I forgot about the 4 magnets on the rotor, concentrated on the measured output frequency on the scope.)

Of course you did not consider that either: no wonder here though because you do not consider several posts in which facts are asked from you to prove your nonsense or made-out claims like:

in Reply #692: "The Tesla serial Pancake coil was patented as an iron ferrite MAGNETIZER COIL!"  or

in Reply #702: "Let me add that the series bifilar pancake or solenoid coil has to be CHARGED initially to reach it's full potential. This is done simply by snapping a good spark across the leads."

Please show evidence where Tesla wrote such claims! 

Or another strange "idea" from you: in your paper clip test you also "charge" the (16 penny) nail (with the bifi coil on it) first, and you do not care that making the nail a quasi permanent magnet with your "charge" treatment you strongly alter the conditions for comparable tests: in the original link you brought in as 'the proof', http://www.tesla-coil-builder.com/bifilar_electromagnet.htm  such "pre-charging" for the nail is simply NOT mentioned. And I already told you: this treatment for the nails is not a repeatable process if done by hand: micro or milliseconds are involved and this defines the strength of the nail magnetization and the time duration of the treatment is uncontrollable by hand.

Yet, it is you who mock members here or you use personal insults like recently "Petro Nazi" to MileHigh in Reply #550 but see #551 too,  what is more in the end of your Reply #552 you insulted Farmhand, the person who asked you to remove the insult, and because he also dared to write "there is no magic in a series connected bifilar coil" you labeled Farmhand as Petrophile too.

If you think you are on the Wild West, then please look for other places to shoot your guns. Till you do not show a meaningful input / output power measurements on your setup that includes the performance of the magical "synchro" coil, there is no sense from you to force it with words and talks and insults.
