A far bigger problem I come across, is mouldy floppies.  Who'd have thought
they'd support mould growth... looks a bit like slightly green grey rings on
the disc surface.  Clags drive heads really badly really quickly. A fairly
common problem on SS and DSDD discs.

Any kind of magnetic field ought to be able to pull the media into
"alignment" magnetically... but that's not going to allow for bit rot, some
of the surface losing is magnetic "permeability"... haven't thought about it
to hard for a long time now... I do recall floppies that wouldn't format, and
or had boot sector virii being cured by strong magnetic fields though.
