30mm O.D x 20mm I.D x 10mm thick N52 Diametrically Magnetized Rare Earth Neodymium Ring Magnets Tube Magnets Big Hole

N52 30mm od x 20mm x 10mm thick Big Hole Neodymium Ring Magnets Epoxy Coated Diametrically Magnetized NdFeB

These large rings are very strong and good for a variety of applications and experiments. They must be handled with care as they will pinch fingers and probably break if they are allowed to slam together. These are currently the largest rings that we stock.

Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet due to their brittle nature, and to avoid injury due to pinching.

PLEASE NOTE:             

• All magnets may chip and shatter, but if used correctly, can last a lifetime.
• Keep away from pacemakers.
• Not for children, parental supervision required.
• COMMERCIAL USE ONLY.
• If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage if magnets join inside the digestive tract.
