Not unless the microwave is in some way defective, if it does then it's
more a hazzard to you than the magnetic media.

Probably not, food near IT equipment is never a good idea.

it would be quicker on a small monitor, the degauss field tends to be
stronger as the coil is smaller for about the same current, but ...

Whatever was on it before for HD disks and usually the same for DD. The
inverse square law for the field means you need linear motor strength
fields before you can approach the field strength found under the head
and reliably erase data.
