Lee Valley has a collection of small ceramic magnets.

My personal favourite is to scrounge old hard drives, though. The mechanism that moves the read/write heads back and forth over the platters contains one or two (usually two) *very* powerful magnets. In newer hard drives, these are ~2-3mm thick, and irregularly shaped, about 2-4 cm on a side.

If you can get your hands on a really old full-height drive, though, you'll find magnets that are dangerously strong. These can be a full cm thick, and 3-5 cm on a side, and strong enough that if your let two "snap" together, they may shatter.

Eh, if I wanted brutally strong magnets, I'd order them online. Get the ones strong enough to break your bones if you put two of 'em together :P

Let's see someone yank one of THOSE off of some awkward part of some bridge-post :P
