Hiya JT, just wanted to share my magnet experience with you. I had a magnet fall out of my mini once... when I pushed it back in, I put it on the wrong side. I was able to remove it by placing the door against the refrigerator
Then I placed a dab of crazy glue in the small hole and placed the magnet correctly. I lifted the residue crazy glue with nail polish remover. So I'm thinking if you use some nail polish remover, you may be able to loosen that magnet to get it out and place it back correctly
