Dangerous Magnets Ltd is your helpful & reputable source for incredibly strong neodymium magnets that NEVER WEAKEN WITH AGE.

Note: I find that CHEAP sources of neodymium magnets from China often have dishonest grade specifications and certification, so I have sourced a supplier where honesty is a top priority.

WARNINGS
- Keep from young children! If two or more are swallowed they can lethally puncture gut tissue.
- The neodymium magnet 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 eg credit cards & pacemakers, keep neodymium magnets at a distance where the magnet field is negligible.

PRODUCT DETAILS

This is a pack of 20 very powerful, neodymium, "rare earth" magnets.

Dimensions: 10mm diameter x 5mm long.

These magnets have a pull/push of around 3.1 kg between magnets, or to 1.32mm sheet steel.

Strength Rating: N45. Many magnets sold in NZ are N35 grade or lower, and are significantly weaker. One trader is advertised a weaker grade as N45, seemingly conned by his supplier.
Neodymium magnets are about 10 times more powerful than traditional, grey, ferrite magnets.

Potential Uses
- School science projects, eg homopole motor, Gauss canon, "Lens effect train", etc.
- Latches & closures, eg wooden boxes.
- Holders (tools, curtains etc)
- Frictionless spring (either tension or compression)
- Attaching documents and products for commercial display
- Use with iron sand or iron filings to learn about magnetic fields.
- Secure display of work-site design drawings to withstand wind. Use two or three stacked for more pull, and easier grip for removal.
- Clamp components while gluing.
- Attachments for reborn dolls

Combine shipping. Quantity discounts available.
