Magnets are great to use in your polymer clay projects. Please note: Magnets lose their strength when they are heated so don't bake them.
Developed in the 1970s and '80s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. There are two types: neodymium magnets and samarium-cobalt magnets.
- All magnets may chip and shatter, but if used correctly can last a lifetime.
- Keep away from pacemakers.
- Not for children, parental supervision required.
- Handle magnets with care. You can easily pinch your fingers. Slide them apart instead of pulling them apart.
- Heating magnets can weaken them.
