It means that it will remove (block) any of your magnetic auras when you equip that treasure (magnetic auras from cookies or treasures and if I'm not wrong even from pets when they grab magnetic jellies), for example Fairy Cookie will no longer have her magnetic aura or if you equip Angel's cookie holly feather it will not work, or at least I think thats what it means :P
