Can somebody explain why is espilon_o called permittivity?
Does it have anything to do with the word "permission"? If
so then who is giving a permission to whom?

Iron does not desire or even need to be magnetized.
However when the atoms and molecules of iron are
completely disorganized, they are "reluctant" to do
so unless they are forced to become aligned . When
forced into a state of alignment, their domain walls
break down and the iron sample exhibits a "permitivity"
to tolerate alignment.
