Well i tell you bro 5khz would make only 10ma to flow or so.... But what i~m saying is that this field should collapse too so it must be charged with current than collapsed

Well that if i understood it well
I made some tests about what i~m, talking regarding the biflar chokes... the waveformes are as i expected to be, square during charging and a peak expponential discharge...
Simple.. .two coils same size, coupled in series with fields adding, so one side connected to positive dc the midle(between coils) connected betwee the transistor drain and ground, and the other side a diode floward biased connected to the cell having its other plate connected to ground... so with no pulsing dc already flows.... because diode is foward biased... during pulse on the diode prevent the cell to discharge and during pulse off the energy goes all to the cell
