Uses for our 4mm x 3mm Neodymium Disc:
Our Neodymium (Rare Earth) magnets have a very high power to size ratio. You will find that even the smallest Neodymium magnet will surprise you with its pull force. Take care while handling these as they will want to join together. If you allow these to join with force they WILL shatter into small pieces.
You will find smaller sized Neodymium magnets are used in a wide range of applications from gate closures, computer sensors and magnetic hard drive disks. With so many uses and due to their high power to size ratio, they are so versatile! Use them around the home, the office or even to hold your tools in the shed!
As a result of these being so powerful and wanting to attract to each other, we must warn you of some potential hazards.
- Magnets can be deadly if ingested, not recommended for children.
- Use eye protection while using our magnets because if two join with force they may break or shatter.
- Magnets can wipe magnetic media such as credit cards, keep magnets away from these to avoid data loss.
