i hate to post anything nasty, filty, or immoral but a while back I was working on a ladies washing machine and found a rather strong magnet stuck on the back of this machine. i showed it to my wife and she fell out laughing and told me to throw it away. she said it was sold in sex shops and was called a bullet. New one on me but listen, that magnet is so strong it works perfect on your application. no, I'm not suggesting hed off to your nearest sex shop but that is one strong magnet my friend. LOL.
