Ramaswami,
a great importance : 1 A to 300 A ! How ?

Conductor:conductor (input-)beginning and conductor-end(-output),conductor length and diameter
Conductor: quantity and turns quantity
Conductor: Ampére-turns ~ RPM strictly to differ from Ampére-conductor-windings/turns
                  https://en.wikipedia.org/wiki/Ampere-turn

10 A conductor or 10x 1 A conductor ( Figuera/Buforn "commutator" : how many connections ?)

how many independant receiving Ampére-coils here,parallel or seriell connection(?) :

from 100 Volt to your recitated 550V : resistor/resistance relation and effect ?

Probably something for your engineering student !?

Asking about Ferrit(iron,not steel) (included Ferroelectric):
in the last years this element became a new "reborn" in the labs with some surprising effect-range
Ferrit-Nitrite(META-material) magnets with up to 100 MGOs as alternative to Neodym supermagnets
and Ferrit crystals as alternative to silicium/silicon "green ferrite",IR-em-waves converting

Dear Sir

We habe seen that it is difficult to get high amperage at lower voltages ad it needs a large iron core. It is easier and cheaper to get high voltage and lower  amperage output.  But what is the type of devices that were in use one hundred year's back is difficult to understand today.

These are large electromagnetic devices and demand a team work of five people tp prepare them.

I am not aware of Ferrit. Is it the same as Ferrite which has zinc added to it and can work at high frequency.  Can you please explain more.

Regards

Ramaswami

french to english translation: " ........rusty soft iron......"

soft ferrit cause low permittivity and remanenz for electro-magnetic purpose with HF(=signals)
~ Met-glas,amorph metals

accelerator are also called collider: how many signals do reach the Target or Particle ?
electro-magnetic bombardement with signals/pulses/waves

The physical (Laplace) operator is called Puls-/Frequency-/Time-/Wave-generator !

HF ~high RPM power densities from motor or generator or transformer up to 1KW/0,1KG
are reachable but this has -later- to become realized by active machine cooling

The self-reliant EBM plant uses its own self-generated electromagnetic fuel. The research and development work of this hi-tech technology began in 1980 in four laboratories in Toronto, Houston, London and in Budapest, managed for ELECTRO ERG LIMITED (EEL) by the GAMMA Group, under Professor L. I. Szabó's leadership.

Sir.

If rusted soft iron is what you ment then I have been using high nreds og kilograms of it already.  When we the experiments if we pour 200 ml water into the cores and conduct the experiments the iron gets rusted in no time what is the big deal.

We found that iron got ionised so fast and water evaporated.  If this is the kind of iron that can also become a permanent magnet it explains why soft iron became a permanent magnet in my experiments though a weak Permanent magnet I now have to heat it to remove the magnetism and hen the rods are slightly heat pour water over them and again apply strong magnetic field through a solenoid to make them strongly magnetised.  880 volts Ac given through thin multifilar coils can make current consumed to be 0.25 amperage in primaries and we can raise the current to 300 volts and 10 amps in one secondary coil or 600 volts and 20 amps in two secondary and three primary coil cores. We can test this using a step up transformer and we can use an independent secondary coil to feedback the primary of the step up transformer. This I can test easily.  But I need to wait for the team to assemble first. We can control the voltage and current in the feedback coil easily. 

So rusted oft iron is all that is needed. I have however ndreds of kilograms of it.

Ramaswami

Cadman,you know it all : 1928 ? Pardon,I do not know it ! Figuera-Buforn generator/ load inrush current relation ?  Only resistive load ?

How about a little reality check

Just ask yourself;

What materials and technology did Señor Figuera have access to? What industrial base existed at that time to manufacture those materials?
