If para magnetic core is used in the place of the ferromagnetic core of the transformer, then what will happen to magnetostriction?

If para magnetic core is used in the place of the ferromagnetic core of the transformer, then what will happen to magnetostriction? Correct Answer be vanished

If the core is not ferromagnetic then the transformer will not operate at all. Thus, humming sound which is produced generally, by a transformer of a ferromagnetic core will get vanished.
