@otto,

I enjoyed the show!

What the hell is going on there? It's like the core slowly builds up some energy and then releases it in a kick when the coil lifts off?

Can you confirm you were injecting one frequency of around 200kHz (pulsed DC using mosfet).

great video otto ...

nice to finally see you ... 

i have an idea for you otto ... and you did say 200khz...


how about you include a magnet in the mix and fire the coil at 180khz... 

ist!

Hello all,

@Yucca

thanks for your kind words.

Sorry, youre wrong. The core and magnet I used only so you can here a vibration. Its the same with or without a core and the magnet. The current is the same, the voltage is the same but with the magnet are the particles a little bit slowed down but not worth to mention.

Today I figured out how and why.

In the next days I will show it to you but I need drawings and time to make them.

Yes, the input was at 200kHz more or less it doesnt matter. The vibration was from 1Hz up to 5kHz or 6kHz. And yes, pulsed with a MOSFET IRFP 450. The connections are already posted in this thread.

@IS

again, thanks for your kind words too.

I dont want to hide myself because ....Im a good looking guy, ha,ha,ha.

you mentioned 180kHz. Yes, but then I need a another sort of ferrite.

The core in the video was a iron powder core and for this, a little bit lower frequency of 180kHz I would need a ferrite core like in oridinary toroidal transformers.

@All

today I will try to make photos of the signals. Its a hard job because the vibrations are not so good to see on a scope.

It seems like magnetic field from coil is made of additive pulses , each one stronger then other. Then suddenly effect is disrupted and that's the moment when coil fails down.
It needs correct frequency of pulses of course.It also resembles famous Edwin Gray demonstrations with pop-up coil.

I think that if you connect a flyback somehow to this circuit and let those pulses flow through primary, the secondary would produce radiant effect on air - electrostatic like field.
Did you used Tesla patents from 1896-1898 about methods of producing high frequency currents ?

A little offtopic but I need an advice.

How can I compute the length of coil knowing only resistance and inductance of coil ? Is that possible at all ? I have to measure exact length of secondary of my old Russian car coil and obviously I cannot dismantle it .
Yes - it is for 1/4 wavelength  to maximize vibrations I suppose
