Dangerous Magnets Ltd is your helpful & reputable source for incredibly strong neodymium magnets that never weaken with age.

- Keep from young children! If two or more are swallowed they can be lethal, by attracting across gut tissue and puncturing it.
- The material is brittle so it can chip or break if magnets crash together. Eye protection advised.
- Magnets can pinch skin and cut clothing.
- For sensitive devices (e.g. credit cards, pacemakers, magnetic recording), keep at a distance where the field is negligible.


This is a pack of 36 amazingly powerful neodymium, "rare earth" magnets, with durable double nickel plating.

Dimensions: 10mm diameter x 1.5mm thick.
Strength Rating: N45. Many magnets sold in NZ are N35 grade or lower, and are significantly weaker. One trader is even dishonestly advertised a weaker grade as N45.

One of these grips to a similar magnet, or smooth, flat steel, with a direct pull of about 1 kg. Stack two, and that pull doubles.
Resistance to sliding on a vertical surface is roughly 1/3 the direct pull.
One magnet holds about 5 sheets of standard A4 copy paper to a whiteboard.

This is a good size for commercial, semi-permanent display boards. (But for easy to grip ones, use our D6x6mm magnets in pairs or even threes.) They can be stacked to make significantly stronger configurations.
For even more strength, consider our D12x2mm or D15x2.5mm.

Potential Uses
- Holders (Tools, curtains etc)
- Attaching documents and products for commercial display
- School or University science projects
- Fastenings for manufacturing photo display items.
- Secure display of work-site design drawings to withstand wind.
- Commercially sewn into curtain seams to hold curtains together or to steel frames.
- Manufacture of name badges (of a non-swallowable size)
