These Neodymium Iron Boron magnets are also known as "Rare Earth or NdFeB magnets". Neodymium magnets are simply incredible! They are up to 10 times stronger than regular ferrite, ceramic, rubber magnet.

What can these magnets be used for?

They are fun to play with, but these magnets have many practical uses as well. Use them on the fridge. Put them to work in the tool shed.Use them as fasteners on cabinetry. They are great for science experiments. You are limited only by your imagination.

Notice:

1. Large neodymium magnets are very strong and must be handled with care to avoid personal injury and magnet damage. Fingers and other parts of the body may be severely pinched by two attracting magnets. The magnets break easily, so please be careful.

2. Never place neodymium magnets near electronic devices.

3. Neodymium magnets are brittle and may flake, crack or shatter if violently knocked together.

4. Neodymium magnets will lose their magnetic properties if heated above 80 degrees Centigrade/176 degrees Fahrenheit.
