Ceramic Ring Magnets

Ceramic Ring Magnets have a high resistance to demagnetization and don't need a keeper.

• High Resistance to Demagnetization
• No Keeper Needed
• Magnets Demonstrate Repulsion
• Barium and Iron Oxide Construction
• Width: 6 mm

They're made of a mixture of barium and iron oxides and are magnetized along their length. The central hole allows them to be threaded onto a pencil or glass rod to demonstrate repulsion.

They may be stacked four-to-five high this way. Each magnet is 6 mm thick and is available in two sizes.
