Sorry for the imprecision - I didn't mean "bound" in the traditional sense. I was thinking in analogy to a metallic conductor that we know from school, where the (valence) electrons are not bound to individual atoms, but idle around inside the metal for all practical purposes - until a current happens. Sorry again, I tend to have rather naive mental models for some physical processes when I don't understand the math behind it.
With "ripped apart" I guess I meant a situation in which we have to drop the assumption of 𝐄=0, because the Lorentz force separates charges faster than the fluid/plasma can conduct. I was wondering if this ever happens macroscopically.
