Dirk had an accident. It took 1 1/2 hours of surgery to remove the shattered bones and repair the damage. Medically speaking, he crushed his right index finger distal phalange. The magnets had a 50 cm (20 inch) separation when they decided to fly together.
He is lucky that he only lost a finger tip as opposed to his whole hand. The block Neo below is about 4" by 2" by 2" N45 with a pull force of around 700 lbs (320 kg). The disk is about 3" dia. by 2 1/2" thick N45 with a pull force of about 400 lbs (180 kg). That is his fingernail and some of his finger tip caught between the magnets.
Holy hellfire. Hit the jump to see the graphic photos and a link to the whole story. Which amazingly didn't include heavy drinking and/or a bet. Seriously though, Neodymium magnets are not playtoys (unless you got the really small weak ones, in which case, whee!). Remember what they taught you in Boy Scouts: if you can't stand the heat, too many chefs spoil the broth. Life wisdom, folks, I'm full of it.
Hit the jump for graphic pictures of a bloody stump.

Thanks to Katie and Devin, who aren't even allowed to play with refrigerator magnets.
