  • This longer magnet is easier to grip to remove from a surface, although once a the length exceeds its diameter, the strength does not increase much. 
  • 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, eg homopole motor, Gauss canon, Levitron, etc.
  • Uses where being able to grip it more easily to pull it off is important.
  • Electric motors & generators
  • Frictionless spring - tension or compression.
  • Attaching products for commercial display.
  • Use with iron sand or iron filings to learn about magnetic fields.


  • 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.
