Why do you specifically want permanent magnets made from "Iron"?
There are far better magnetic materials for most permanent magnet applications so finding ones that are pure iron may be difficult.
If you share what application you need a permanent magnet for, we can probably advise you on where you can buy suitable ones.

Hobbie stores are one source for magnets. They typically stock various shape magnets (horse shoe, U, bar, and various sized button).
Radio Shack stocks bar magnets.
Craft stores typically stock magnets for use in making decorative "refrigerator" magnets.

All of the suppliers listed here:
http://sciencebuddies.org/mentoring/pro ... lies.shtml sell permanent magnents. I would personally reccomend Edmund Scientifics because they have a large selection of permanent magnets at reasonable prices.
