Dangerous Magnets Ltd is your helpful & reputable source for incredibly 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. Larger ones, or small ones in large groups, can crush fingers.
- For sensitive devices (e.g. credit cards, pacemakers, magnetic recording), keep at a distance where the field is negligible.

The pull between 2 of these, or to flat, 1.7 mm steel plate, is around 4.5 kg.
The pull when between two steel plates is around 19 kg! In the photos a bicycle, attached to a heavy steel anvil, is held up by 2 of these magnets.
