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.
