Proof of concept - perturbing a static magnetic field

[EMdevices]

This setup by brnbrade is amost exact to my tesla coil video I showed.

You have a secondary and you have a few turns for the primary.

The only big difference with my setup was that I used a small blocking oscillator to create a train of spikesÃ,  (which contain a number of frequencies in their Fourier decomposition) and can exicte a number of resonances that may exist.

The other small difference was that I used a ferite inserted in the center of the tube.Ã,  He seems to be inserting a magnet.Ã,  And also he is placing a disk magnet.Ã, 

My ferite on the outside of the tube did nothing.Ã,  But it looks like a magnet disk will do something.

Now, I'm wondering about his claim of 250 Volts and 1 Amp.Ã,   I saw spikes on my scope that were realy high as well, but I doubt the 1 AMP constant flow.Ã,   You just can't hook up a regular ampmeter to some RF source and have any relyable reading.

Air core only.

OK, I went back to your description of how you wound your coil, and I see now why you are getting this reduction.

It should not matter if your static field coil is N-S or S-N in regards to the diminished induction effect it is having with your "transformer". In fact, if you short the two leads of this static coil, it will again have this effect on the induction.

Reason? This static coil is acting as a load on your "transformer".

Might be best to use a permanent magnet for the static field.

Thanks Darren for your explanation. I'd moved onto a permanent magnet setup last week and had some interesting results. I've had on one occasion, a suddenly appearing AC sinewave, on an output coil,  with a fixed amplitude, no decay or ramp up. It appears and disappears. There is no rhyme or reason. Almost impossible to capture on a camara - believe me I've tried!!

More on this in a little while.

Good morning guys, 

brnbrade had an air core, no magnet inside, only a circular permanent magnet around outside.  Even without that he was getting voltage!

Next, as I told everyone,  I had someone send me a very similar story that happened to them two days ago  (sent to me two days ago).  They also used a FM radio, except they put the earphone right onto the input wires.  Let's just say that output was not the problem..LOL   Control was.

I even wrote Rob and others before all of this asking the difference between this and what we have been doing, as far as the wave input is concerned.  So to me brnbrade is a second confirmation, which jumps the "believability factor" in my mind.

I would suggest to all to immedietly test this!  Theorize later.  Think TPU, Think Magnetic field OVER/AROUND the toroid @ 7.23 Hz as I have been saying all along.  But test this brnbrades way.  Seems easy.  We just have to guess at the size wire and size pipe.  (P.S.  This is why proper documentation of experiments is so important, for replication purposes.  Please document properly!  Thank you!  LOL

Cheers,
Bruce

So you input the frequency with a wire from the headphone jack, and not connect the ground?

This is odd. Surely, the output from the headphone jack is music, i.e. audio frequency
stuff between 40 hz and 18khz.
