Magnets 3x4 mm Neodymium Discs 3mm diameter x 4mm thick
- Spider Magnetics strong N35 grade (NdFeB) neodymium magnets
- Each magnet has a vertical pull of 249g flush to a mild steel surface
- The North and south poles are on the flat faces
- Triple plated Nickel-Copper-Nickel for optimum corrosion resistance
Neodymium magnets are surprisingly strong for their size. Our magnets are triple coated nickel-copper-nickel for good corrosion resistance and magnetised axially giving a north pole on one flat face and a south pole on the opposite.
IMPORTANT SAFETY NOTE: Neodymium magnets can be harmful if inhaled or swallowed so please store them safely out of reach of children. For children's projects use them strictly under adult supervision.
