Miniature 3mm dia 4mm long cylindrical disc magnet manufactured from Neodynium Iron Boron which provides a powerful magnetism and exceptional resistance to demagnetisation.
Each magnet has a vertical pull of 0.26kg flush to a mild steel surface making them ideal for use in magnetic uncoupling systems when fitted between model railway sleepers.
These magnets are magnetised axially giving a north pole on one flat face and a south pole on the opposite face.
Triple plated Nickel-Copper-Nickel for optimum corrosion resistance.
IMPORTANT SAFETY NOTE:
Neodymium magnets can be harmful if inhaled or swallowed so please store them safely out of reach of children. If swallowed seek medical help immediately.
For children's projects use them strictly under adult supervision.
