> Trapped electrons vs magnetic regions;

From the physics point of view, aren't both cases the same thing?.

Isn't magnetic regions a state of the electric field? so if I move electrons in and out, the electric field should be changing as well

No. A region of a piece of material is magnetized in a certain direction when its (ionized) atoms are mostly oriented in that direction, the presence of a constant magnetic field is (roughly speaking) only a consequence of that.

So flash memory is about the electrons, while magnetic memory is about the ions.

Aren't permanent magnetics a direct result of oriented spins? (So due to quantum effects?)
