and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Well, now that you asked that, I am a bit puzzled because I have not done any tests with segmented core electromagnets.  Segmentation has never been an issue with cores,  I am not aware of practical solutions applying segmentation in electromagnet cores. 
All I can logically think on possible drawback, hence possible decrease in magnetic field, is the air gap between the segments that impose much higher reluctance for the flux than the core itself.  And if you do your best to match the facing surfaces of the segments to reduce the air gap than you pretty much approach the single solid core case, with no segmentation...

I wonder why using segments for a core is needed?
