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.

Items ordered and paid for after 12 noon or over the weekend are sent on the next working day. We never charge excessive amounts for postage and packaging.

EU CUSTOMERS IMPORTANT: You are will be required to pay import VAT (tax) at your local rate to your postal delivery service before any goods are delivered. Since 2021 you have not been charged British VAT (at 20%) on any purchases, however, with effect from 1 January 2022, the rules regarding importing from outside the EU changed and import VAT is now payable on any value of goods imported into the EU. This is separate to any tariff which may or may not be chargeable on the goods due to their country of origin. Please also note that we are legally required to declare the correct value of your purchase which is used to calculate the tax and any tariff duty. Failure to pay the import charges will result in the goods being returned to the UK.
