What is a Magnetic Drum? - Definition from

Magnetic Drum: A magnetic drum is a magnetic storage device used in many early computers as the main working memory, similar to how modern computers use random access memory (RAM) cards. In some cases, magnetic drum memory was also used for secondary storage. It is basically a metal cylinder that is coated with a magnetic iron-oxide material

Dry-Erase Boards - K&J Magnetics

A magnetic whiteboard has the white surface deposited on top of a thin layer of steel sheet-metal, instead of particle board or MDF. Since it has steel behind the thin plastic, magnets stick quite well to it. It's easy to tell if your whiteboard is magnetic: not only do magnets stick to it, but the ones with a steel backer are much heavier.
