The 10×5mm Round Neodymium Magnet is an N35 grade NdFeB permanent magnet in a 10mm diameter cylinder with 5mm height, silver nickel finish, designed for DIY, acoustic, and electronics builds. This Neodymium Magnet’s round disc shape offers a mounting advantage over square block magnets covered separately — the 10mm cylindrical body press-fits into a standard 10mm diameter drilled hole, making it easy to embed flush into wood, plastic, or aluminium panels without requiring a milled rectangular slot.
The small neodymium magnet’s 5mm height relative to its 10mm diameter gives it a 0.5 thickness-to-diameter ratio — significantly thicker than the 10×10×2mm square block’s 0.2 ratio — which means this round cylinder has more magnetic material volume and a stronger axial pull force through its circular pole face than the thinner square block despite similar outer dimensions. This makes these neodymium magnets well suited for Hall effect sensor positioning builds, where a cylindrical neodymium disc is commonly used as the rotor trigger magnet because its round profile produces a predictable, symmetric magnetic field pattern around the cylinder axis that Hall sensors can reliably detect during rotation.
the 10mm round form factor means these strong neodymium magnets cannot tile seamlessly edge-to-edge against other round magnets the way square blocks can — for applications requiring a flat continuous magnetic surface, the square block variant is better suited. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices.
