Magnets 20x3 mm Neodymium Discs 20mm diameter x 3mm thick
- Spider Magnetics strong N35 grade (NdFeB) neodymium magnets
- Each magnet has a vertical pull of 3120g 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.
IMPORTANT SAFETY NOTE: If you allow neodymium magnets to crash together or into metal objects the force may shatter them. Please take care handling them.
