Magnets 4x1 mm N52 Grade Neodymium Discs 4mm diameter x 1mm thick

Spider Magnetics strong N52 grade (NdFeB) neodymium magnets Each magnet has a vertical pull of 233g 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.
