Currents induced in a conductive material are a function of the magnetic field being imposed on the material and its electrical resistance.
Putting holes in a subject material increases the electrical resistance. Hence the resulting field will be weaker.

You aren't physically changing the coppers properties by cutting holes into it though. Why doesn't the field induce many smaller loops of current?

You're changing its structure and the field is both a function of its properties and its structure.
