The 8×1.5mm Round Neodymium Magnet is an N35 grade NdFeB permanent magnet with 8mm diameter and 1.5mm thickness, silver nickel finish, in a coin-cell style disc profile designed for DIY and electronics builds. its mini cell magnet form factor closely resembles a coin cell battery in physical appearance, making it the natural choice for applications where the magnet must be embedded in very thin panels, PCB or wearable enclosures with minimal depth clearance.
This neodymium magnet electronics use case benefits from its ultra-thin profile — at 1.5mm thick, it sits nearly flush inside shallow routed pockets or thin 3D-printed housings that would not accommodate the 2mm square block or 5mm round variants. These strong neodymium magnets are also used in PCB surface proximity sensing where a thin disc triggering a reed switch or Hall sensor needs minimum standoff height above the board.
the 1.5mm thin disc has the lowest magnetic material volume in the lineup, giving lower absolute holding force than the thicker neodymium magnets — it suits lightweight closures and proximity sensing, not heavy-duty magnetic clamping. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices. This round neodymium magnet is ideal for DIY projects, robotics applications and STEM models.
