The 20x2mm Round Neodymium Magnet is an NdFeB permanent magnet with 20mm diameter and 2mm height, silver nickel finish, in the largest round disc form in StemVolt’s magnet lineup. This Neodymium Magnet’s 20mm diameter gives it a pole face area of approximately 314mm² — nearly double the 15mm disc’s 176mm² — making it the strongest face-pull thin disc magnet in the range at the same 2mm profile thickness.
The round neodymium magnets 20mm diameter creates a symmetric wide-area magnetic field that suits large panel magnetic closures, wide reed switch actuation zones, and STEM magnetic field demonstrations where a larger field footprint is needed. These neodymium magnets fit into 20mm diameter drill holes or circular pockets for flush-panel mounting, and their neodymium magnet electronics use includes position markers on larger rotating assemblies and display-case magnetic latch builds.
with the largest face area, this strong neodymium magnet generates the highest attraction force in the disc range — separating these neodymium magnet for diy project builds requires careful sliding apart rather than direct pulling to prevent chipping. Available from StemVolt, your trusted destination for robotics components and STEM DIY kits at competitive prices.
