Dangerous Magnets Ltd is your helpful & reputable source for extra 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.
- For sensitive devices (e.g. credit cards, pacemakers, magnetic recording), keep at a sensible distance, i.e. where the field is negligible.

PRODUCT DETAILS

This is a pack of 120 tiny, really powerful (for their size), neodymium, "rare earth" magnets.

Strength Rating: N52, the strongest magnet material made. Many magnets are N35 (even when specified as N45!) which is a considerably weaker grade.
One magnet releases another (or 0.38mm steel sheet) at about 130 grams before it releases. Between two sheets of steel, 420 grams!
A single magnet can hold up one (actually two - just) A4 sheet on a whiteboard, but they are too small to easily to remove. For easy-to-handle magnets on whiteboards, I recommend our D6x6mm, use in pairs. Or D4x4 in threes.

Dimensions: 3mm diameter and 1mm thick. They are plated nickel over copper over nickel for durability.

Potential Uses

- Latches & closures (Wooden boxes, doors, etc)
- Frictionless spring (either tension or compression)
- Triggering reed switches and other actuators
- Warhammer etc. For attaching parts of models or for Movement trays.

If you prefer half a pack of these, along with half a pack of D2x1mm or D2.5x1.5mm or D4x1.5mm or D5x0.5mm, or others, Priced at the higher of the two packs, then do a buy now of this auction, and before you pay, ask me to make this change and send you a modified invoice with payment options. (And extra half packs if you wish.)
