All ferrite ringmagnets on this page are axially magnetized. This means that the poles are respectively located on the flat circular surface.
Ferrite or neodymium magnets?
Compared to neodymium magnets, the adhesive force of ferrite magnets is much weaker. On the other hand, they are cheaper, suitable for outside use (rust-resistant) and can take heat up to 250 °C. If size and volume are less important than price, ferrite magnets can be a good alternative to neodymium magnets.
Magnets of hard ferrite are the cheapest and best known types of magnets. Their raw materials are basically ferric oxide and barium or strontium carbonate. Magnets of ferrite can be isotrope or anisotrope energy density of the latter is about three times higher. We offer anisotrope ferrites only. You find different shapes: rings, block, discs and rods - and U-shapes (horseshoe magnets).
