Product Details

Size: 12mm diameter x 16mm long

Quantity: 4

Grade: N45 Neodymium

Pole location:  Poles on flat faces

Pull/Push: About 6.6kg between each other or to 2.1mm sheet steel

Notes:

• 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.

Warnings:

• 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.
