Product Details

Size: 12mm x 12mm x 12mm Cube

Quantity: 4

Grade: N45 Neodymium

Pole location:  2 opposite flat faces of the magnet

Pull/Push:
About 7.9kg between each other or to 2.3mm sheet steel.
The second photo shows both a 8.4kg steel cylinder, and a 5kg anvil easily lifted by two of these.

Notes:

• 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

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.
