Product Details

Size: 20mm diameter x 7.2mm thick Pot magnet with 4.4mm hole

Quantity: 6

Grade: N45 Neodymium

Pole location:  Pole on flat face

Pull/Push: About 7kg to 2.2mm sheet steel. Resistance to sliding, about 1/3 of that. 

Pot magnet details:

• Specialised "Pot" construction
• A neodymium magnet housed in a steel “pot”
• Extra durable
• The highly-localised field is across a narrow ring on only the countersunk side
• They pull best to flat steel, eg thick washer
• Not for pulling from a distance, or to another magnet, or motors - use a STANDARD magnet for that
• Still pulls strongly when set into steel.

Notes:

• This is not a standard neodymium magnet, it is a Pot Magnet
• 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:

• Holding tools, knives etc
• Closures for doors etc. Sorry I don't have washers
• Holding panels & fittings to steel walls
• When magnetic fields must be kept to a minimum

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.
