Economy bar magnets with keepers.
Perform a variety of activities and experiments involving magnetism.
The magnet keeper helps preserve the strength of the magnet by completing the magnetic circuit, and is particularly useful for economy magnets like these. Keepers also have a useful safety function as they stop external metal being attracted to the magnet.
