Anisotropic Strontium ferrite ceramic 8 material. These craft magnets are stronger than your average craft magnet. Ferrite magnets do not conduct electricity unlike Alnico, NdFeb and Smco. In order for them to conduct electricity a silver coating needs to be applied.
These magnets are suitable for the following applications:
- images
- moulding clay
- wood
- plastic
- and other craft and educational projects.
WARNING: We would not recommend this magnet be used by children under 3, and not by children under 5 without supervision.
