Magnets out of computer hard drives are rare-earth and come in 2's (Wickedly strong, don't get your fingers caught between them) and easy enough to come by.
There are some you-tube vids on how to remove them - google removing hard drive magnets
Ive pulled a few of these out of hard drives, they are also the first magnets to smash and cut the crap out of your hands being very thin and frail i did manage to get one out perfectly round and superglue it to the end of the pick which was super handy at picking up small junk. But if i was to buy them again id go straight to ebay and get a solid one that doesnt shatter.
