Bloch wall disconnect and reconnect. The final design!

@all

Correct me if i am wrong ...

Ok the core of a transformer will conduct electricity if there is a change in the magnetic field up to saturation regardless of the power source dc or ac , 5 volts or 5000 , the freq of the change in the field will change the amplitude of the output , the turn ratio also but to me it is where most of the losses happen ...

The core is the limit ? yes ?

Now how dose DC saturate a core compared to AC , they are 2 different beast , now lets say i send a AC signal in a core ex : 20 volts 10 mili , but also bring in some DC , this should bring the core closer to saturation wouldn't that that give more current ... and what happen to the voltage .

How could i use a core rated at many amps , and still make a decent Joule thief from 1.5 volts DC ...

Toroid core where used in logic computer circuit has adder , hard to imagine but that was done between 1950-1960 , now only the army uses it .

@MK1,
Your questions are right on schedule.
I posted this:

I used a small toroid and the spark was copied 2 more times.
I put in that bigger toroid and I saw no spark. Even with mixing the different windings around. The iron core seems to suck it all up. The potential never seems to build up to cause the jump.

Nice video , it seem the toroid is drawing electrostatic potential from the surroundings , dose it do it if you reverse the polarity from one of the coil on the mag amp.

I have to say its not the type of magamp i know .

I got this link that is quite informative on the magamp subject , i am sure it got edited some of the good parts are missing , but if you read carefully the words chosen you will see the potential ,http://avstop.com/AC/apgeneral/MAGNETICAMPLIFIERS.html

The mag amp is acting like a transistor and not like a transformer ...

@MK1,
I don't have the control in there. I am adding that 5khz next.

Is magnetic amplifier kind of parametric oscillator with a valve ?
