	I'd rephrase that to say that:
		Air will not magnetically saturate.
	For a given volume, tho, more flux (roughly:
	energy) is handled with a 'magnetic' core than with an
	air core, and better control of stray fields is
	achieved.  Using the magnetic core DOES mean
	watching for saturation effects.
