Shawn,

The core never saturates, it just increases the inductance when
it's in place and limits the current that way.  If the core could
saturate, it would increase the current.  NST's or other transformers
that use a saturable core work a different way.... since the saturation
shunts the magnetic field so the secondary receives less of a field,
and therefore delivers less current (than it would if the core didn't
saturate).
