  • Rectangular shapes pinch fingers and chip more easily than do cylindrical shapes
  • About 10 times more pull than the traditional, grey, ferrite type
  • This type of magnet never weakens with age
  • Triple plated for durability: Ni/Cu/Ni

Potential Uses:

  • Clamp components while gluing
  • School or university science projects, e.g. levitron
  • Cover with card then iron filings or iron sand to show different fields on the faces
  • Make a Halbach array for levitating pyrolytic graphite


  • Not for kids! Two or more, if swallowed, can lethally puncture gut tissue.
  • They can pinch skin and cut clothing.
  • The material is brittle. It can chip or break during collisions. Eye protection advised.
  • For credit cards, pacemakers etc, keep at a distance where the field is negligible.
