Hi, you can find potent rare earth magnets in hard drives. i just took a
commercial hard drive apart and there were 4 awesome strong magnets and
quite large. I had to use a pry bar to get them apart. be careful!! one of
my friends put one on a finger jokingly and then started to scream it took 4
rescue workers to remove the magnet(he was in dyer agony for 7 minutes!)the
finger is ok but the shape will never be the same. cul brian f.
