Safety Warning
Neodymium magnets are brittle, super strong, easily shattered and broken, Here are some tips that will help when working with neodymium magnets: |
1. Wear eye protection and gloves when working with magnets if necessary. |
2. Slide the magnets rather than pulling off the stack. |
3. Keep away magnets from kids in case accident happens. |
4. Keep away magnets from objects that might cause damage like smartphone, GPS, pacemaker or other electronic devices. |
5. Do not put magnets in high temperature environment, magnets will demagnetize while they are over heated. |
6. Magnets can rust and get scratched because magnets contain iron and mostly are nickel plated. |
