Product Details

Size: 10mm diameter x 5mm thick with 3mm countersunk hole for mounting

Quantity: 12

Grade: N45 Neodymium

Pole location:  Four countersunk on North face, four countersunk on South face, so they can attract or repel.

About 2.5kg to another magnet or to 1.3mm sheet steel. Resistance to sliding is about 1/3 that.


  • 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:

  • Simple mounting without adhesive.
  • Holding tools etc to a surface.
  • Small cupboard closures, either face to face or gliding sideways towards each other. (Next larger sizes with holes: D12x3 & D15x4.)
  • Good size for science demonstration of repulsion when threaded to a 3mm non-steel rod.


  • 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.
