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

I trade with scrupulous honesty.

- Keep from young children! If two or more are swallowed they can lethally puncture gut tissue.
- The material of neodymium magnets is brittle so it can chip or break if magnets crash together. Eye protection advised.
- Neodymium magnets can pinch skin and cut clothing.
- For sensitive devices, e.g. credit cards & pacemakers, keep neodymium magnets at a distance where the field is negligible


Neodymium magnets are about 10 times more powerful than traditional magnets.

A pack of 32 super-strong neodymium magnets, also called "rare earth" magnets, plated copper/nickel/copper for durability.

Size: 6mm diameter x 6mm long.

Strength Rating: GENUINE N45. Most neodymium magnets are made in China, where there are many suppliers. I have bought CHEAP N45 magnets from China which were definitely weaker than stated, so I have meticulously selected a supplier who is honest about the grade and quality of these neodymium magnets.

Pull/push: About 1.4kg between magnets. Same pull to 1mm sheet steel.

This is a good shape of neodymium magnet for mounting into a hole by epoxy-gluing, or better still, jamming.


- Closures, eg for wooden boxes, etc
- Rolling together as detachable hinge
- Educational science projects
- Frictionless spring - tension or compression
- Attaching documents and products for display
- Easy-to-handle size for whiteboards, used in pairs. One pair holds up to 10 pages of A4 copy paper.

I'm happy, after the auction, to change your single neodymium magnet purchase to 2 HALF-packs of different sizes of neodymium magnets.
