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

WARNINGS
- 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.

PRODUCT DETAILS

Dimensions: 6mm diameter x 1 mm thick. Plated nickel/copper/nickel for durability.

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 300 grams. Stack two, and that pull doubles.
Resistance to sliding on a vertical surface is roughly 1/3 that direct pull.
One magnet holds 3 sheets of standard A4 copy paper to a whiteboard.

Potential Uses

- Latches & closures (Wooden boxes, etc)
- Frictionless spring (either tension or compression)
- Triggering reed switches and other actuators
- Attaching documents and products for commercial display
- School or University science projects
- Fastenings for manufacturing photo display items.
