A changing magnetic field produces an electric field. How this electric
field affects the electrons in a given material depends on the
properties of the material. For a metal, where many for the electrons
exist in a sort of "sea" of electrons bound to the metal but not to any
particular atoms, the electrons are free to move around as determined by
the electric field and a current is produced. In a non-metallic
material, where the electrons are bound to atoms, the electron
wavefunctions and energy levels will be affected by the electric field
but (barring an exceptionally strong electric field) the electrons will
remain bound to the atoms. So, no current.
