1 Pack NdFeB Magnet Ring OD 10x4x10 mm Diameter 0.39'' Round Strong Magnets Axially Magnetized NiCuNi Coated Rare Earth Magnets

The ring magnet is the staple in most of our sculpture kits. The rings can be stacked to form longer supports between balls for almost infinite sculpture possibilities. The hole in the middle keeps the steel balls perfectly aligned in the ring. Two or more of these rings on a stick or string repelling each other can be quite entertaining and educational. Fun for all ages.
