Product Details

Size: 50mm x 25mm x 12mm thick block with two 4.3mm countersunk holes for mounting

Quantity:  1

Grade: N45 Neodymium

Pole location:  Poles on large faces of the magnet

Pull/Push: About 35kg to 4.7mm steel plate. 60kg for a stacked pair. Resistance to sliding is about 1/3 of these figures.


  • If the magnet is too strong, glue 1 or 2 mm thickness of a non-magnetic material to the pole surface
  • 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:

  • Securely attaching all manner of fixtures to plate steel, or for a heavy gate. Consider the cheaper "pot" type especially if the steel is thinner.
  • Retrieve or "fish" for lost steel items
  • For making a "sweeper" magnet
  • Making wind generators


  • 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.
