Do you mean an SD card or a micro-SD card of the sort the Kobo uses? If the former, that's still a lot bigger than the magnet I've been using.
The Kobo does not use a magnetic hard drive for storing books or software, so it seems unlikely that you would corrupt your data. However, I'm not an electrical engineer and I'm not qualified to give you advice on using such relatively powerful magnets with the Kobo. Anyway, it sounds as if you have your mind made up. Good luck.
