Is it on with sticky pad, glue ...? If it hasn't gotten loose from the light being on ( heat) I might try putting my iron on the magnet and see if that loosens the glue? Be carefully not to get heat on the sewing machine paint! Next I would try hairspray or goo gone to see if it would dissolve. If that doesn't work I would the try something stronger like turpentine but that might take the paint off too.
