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.

This pack contains 40 super-strong neodymium magnets, also called "rare earth" magnets, plated copper/nickel/copper for durability.

Size: 5mm diameter x 3mm thick.

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: One of these neodymium magnets grips to a similar magnet, or smooth, flat 0.8 mm steel, with a direct pull of over 0.7 kg.

A good shape for gluing/jamming into a hole


- Latches & closures, eg for wooden boxes
- Holders, eg tools, curtains etc
- Rolling together as detachable hinge
- Triggering reed switches and other actuators
- Set into perspex sheet for photo displays.

I can supply 2 or more HALF-packs of neodymium magnets. Buy a full pack, then before paying, request the change by email. Then I'll send you an amended invoice with payment options. (Add extra half packs to any order if you wish.)

Combine shipping. Bulk purchase discounts.
