Q: What are rare-earth ring magnets made from?
The magnets are made from neodymium iron boron (NdFeB). Neodymium has one of the highest magnetic properties of any magnetic alloy, and the magnetic force increases with the magnet's dimensional size.
99K3701 - 1/4" x 1/8" (1/16") Ring Magnet
This item is not available for this region.
Until you have actually used rare-earth magnets, you cannot appreciate their strength. The strength of these magnets has to do with the electron array in the neodymium, the rare earth they are made from. This force only increases with the magnet’s dimensional size.
Ring magnets stack wonderfully on a rod or a taut cord if you place them with similar poles facing. You can design an awe-inspiring horizontal top by putting two ring magnets on a rod and hiding four magnets in the horizontal base.
There are hundreds of uses for these magnets. Nickel plated with slightly rounded edges, they can be glued in place with almost any glue (epoxy is the most secure).
Dimensions given are outside diameter by thickness, with inside diameter in brackets.

Ring magnets can be glued in place with almost any adhesive. Epoxy gives the most secure bond and is the recommended option for permanent installations. The nickel-plated surface bonds reliably to most glue types.
Yes, ring magnets with a 1/4" inside diameter can be combined with rod magnets. Stacking them on a rod with like poles facing creates a floating or repulsion effect useful for mechanisms, demonstrations and kinetic projects.
Ring magnets are available in multiple sizes with outside diameters from 1/4" to 1". Each size is listed with its outside diameter, thickness and inside diameter. Choose the size that matches your application's holding requirement and mounting constraints.
