No, the scientists concluded that there
MAY be a salt water ocean. Nowhere in all the articles I searched through on Europa mentions that it is too small for an iron core. Their observations of the changing magnetic field shows evidence of water, not that water is causing a magnetic field.
Nice try though.
Here is an
article on Europa that even has a diagram that shows a metalic core.
