Magnets 25x10x3 mm Neodymium Blocks 25mm x 10mm x 3mm thick
- Spider Magnetics premium N52 grade (NdFeB) neodymium magnets
- Each magnet has a vertical pull of 4.23Kg flush to a mild steel surface
- The North and south poles are on the larger 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.
These magnets have a variety of uses in holding and modelling applications. Having a very high power to weight ratio also makes them very useful as traction magnets for slot cars (please check that this size is correct for your car as models vary)
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.
