One 20 mm disk magnet
One 20 mm disk magnet Quantity in Basket: None
Price: $4.83
Shipping Weight: 0.20 pounds
These are larger magnets made of the same alloy of Neodymium, Iron, and Boron as our 12mm cube magnets.

These are ideal magnets for use in the 10 Minute Rail Gun project, or as toys by themselves.

They are plated in gold to seal the sensitive alloy from moisture. They are 2 centimeters in diameter, and 3 millimeters thick.

CAUTION: Neodymium magnets are so powerful that they will break if allowed to jump together, especially these large thin discs. Work with them on a steel surface to prevent jumping.
