A 720K 3.5" is about 600 Oersted;
a 1.4M 3.5" is about 720-750 Oersted.
You can format a 1.4M as 720K, and often, maybe even usually, get away
with it; it will be just like a poor quality 720K.
On drives with a media sensor, you can cover the hole during formatting.

Having grown up with 1.44MB 3.5" floppies, I have a question: is it
possible to use a 1.44MB disk and just format it as a 720K disk?
