Magnet Keeper

A magnet keeper is ferromagnetic bar placed across the poles of a permanent magnet that helps preserve the strength of the magnet by completing the magnetic circuit, and are particularly useful for magnets which have a low magnetic coercivity?, such as AlNiCo magnets.

Keepers also have a useful safety function as they stop external metal being attracted to the magnet. Wikipedia, Magnet Keeper (external link)
