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 at a distance where the field is negligible


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

This pack contains 96 super-strong neodymium magnets, also called "rare earth" magnets, plated with copper/nickel/copper for durability.

Size: 3mm diameter x 3mm long.

Strength Rating: GENUINE N45. I have bought CHEAP N45 neodymium magnets from China which were definitely weaker than stated, so I have selected a supplier who is honest about the grade and quality of these neodymium magnets.

These neodymium magnets have a pull (or push) of around 0.29 kg between magnets, or to 0.5 mm steel sheet.

- Latches & closures, eg for wooden boxes.
- Holders (tools, curtains etc)
- Frictionless spring (either tension or compression)
- Triggering reed switches and other actuators
- Educational science projects

For stronger magnets, consider our D4x4mm or larger. For smaller, we can offer D2.5x1.5mm or D2x1mm.

I am happy to supply 2 or more HALF-packs of magnets, eg D2x1, D2.5x1.5, D3x1, D3x3, D4x1.5, D4x4, D5x.5, D5x3 etc. Buy a full pack, then before paying, request the change by email. Then I will send you an amended invoice with payment options. (Add extra half packs to any order if you wish.)
