These tiny magnets are made of the same alloy of Neodymium, Iron, and Boron as our 12mm cube magnets.
These are small magnets for use as the floating magnet in the Magnet in Mid-air project, or in the Curie Effect Heat Engine.
They are plated in gold to seal the sensitive alloy from moisture. They are 2 millimeter cubes.
This makes a good sample for Gold, Neodymium, or Boron
in your collection of samples for the Periodic Table
of the Elements.
CAUTION: Neodymium magnets are so powerful that they will break if allowed to jump together. Work with them on a steel surface to prevent jumping.
