32mm dia Ferrite Pot Magnet with 5mm central counter-sunk through hole and a pull force of about 7lbf.  Comes with a plastic spacer and a keeper which is chrome plated with thickness 2mm. The spacer and keeper do not have a through hole.  A Ferrite magnet obviously contains Iron, and hence is potentially subject to corrosion if exposed to moisture.  Contact us if you require a different, possibly plated magnet surface.
