I have a few of these and they have a lot of strength to hold themselves together. I would figure it would be enough for this use anyhow.
there are lots of options with sizing;
so you want to use magnetic force to hold the magnet in place? bad idea. use one magnet and epoxy it in place or use one of the magnetic rotor bolts.
