Spider Magnetics strong neodymium magnets. The magnets in this listing are grade N35. These magnets are triple coated nickel-copper-nickel for good corrosion resistance and these magnets are magnetised axially giving a north pole on one flat face and a south pole on the opposite face. Size: 20.0 x 3.0 (+/- 0.1mm).
Surface Flux Density: 172 mT. Max Vertical Hold: 624 g. Holding force values are calculated for this size and shape of magnet. It represents a maximum value for comparative purposes.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. Customer Notice: Neodymium magnets are made from metallic powders that are pressed into shapes and treated in a furnace. These shapes are then electroplated with nickel to prevent corrosion. The shiny nickel coating gives the impression that the magnets are made of solid metal but they are physically more like pottery. Depending on their size and shape if you allow neodymium magnets to crash together the force may shatter them. We try our hardest to get your order to you as quickly as possible.
This charge is made at the discretion of the receiving country and is your responsibility to pay. But please note the following to avoid confusion. Please then only return items to the return address provided and not the address on the package as this will greatly delay receipt. Failure to re-use the original package may result in transit damage.Neodymium magnets are made from a sintered alloy of the rare-earth element neodymium with iron and boron. This material has very high energy and is stronger than any other permanent magnet material for most applications. Neodymium magnets are manufactured in a large number of grades. The material grade determines the energy and thermal characteristics of the magnet. The numeric value in the grade code 35,42,52.. Represents the maximum energy of the material and any following letters represent the thermal characteristics. Neodymium magnets have a huge number of uses in crafts and hobbies and you will find them in many industrial and household products but they are not suitable for every application.
