These very small but powerful 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 6 millimeters in diameter, and 2 millimeters thick.
CLassrooms often need fifty at a time.
