Magnetic Or Electric Field Amplification, Just By Adding Metal Or Dielectric Material

Magnetic Field Amplification

Imagine you have a row of  ferrous-metal-dominoes, each one slightly large than the other ( according to some formula ? ),   and then apply an  electromagnet  to the start of the row where the smallest domino is .
    This  electromagnet should only be strong enough to ONLY turn the first domino into a magnet ( otherwise this domino amplification idea would be pointless ) .
    - If you've used THE PRECISELY correct proportions of increasing size dominoes,  I wonder if you could get the largest domino at the end of the row to turn into a magnet ?

   I'm more or less sure that the above  'Magnetic-Field' set-up should not function successfully,  because you have to overcome  resistance in each ferrous-metal-domino before the permeability allows it to turn into a magnet .

Electric Field Amplification

But what about the electrostatic ( CHARGE-SEPARATION ) equivalent of this experiment.
In each dielectric-domino there  'may'  be less resistance to it's  charge-separation  than there is in the   magnetic-field experiment .

If either of these experiments worked, then you could possibly achieve massive magnetic or electric fields just by using small voltage?/current?
