So I was thinking about similarities in the nature between these two which could justify similarity in the nomenclature.
So, diamagnetic materials are those whose atoms do not have permanent magnetic dipols, so when you apply magnetic force on them, they create local dipole oriented ANTIPARALLEL to the external magnetic field. That's why the magnetic susceptibility of diamagnets is negative.
Dielectric materials, similarly, are those whose atoms do not have permanent electric dipols, so when you apply electric force on them, they create local dipole oriented ANTIPARALLEL to the external electric field. But, for some reason electric susceptibility of dielectrics is always positive!
Second thing, when an atom has a permanent magnetic moment we call it a paramagnet, but when an atom has permanent electric moment (in.e. water) we call it again a dielectric.
I'd like to hear your opinion on this one.

Pero
