20x5x2mm Rectangular Neodymium Magnet – Strong Rare Earth

The 20x5x2mm Rectangular Neodymium Magnet is an N35 grade NdFeB rare earth magnet with nickel coating, measuring 20mm long, 5mm wide, and 2mm thick, in a narrow elongated bar form for DIY and robotics builds. This Neodymium Magnet has a 4:1 length-to-width aspect ratio — significantly more elongated than the 20×10×2mm rectangular variant covered separately, giving this narrow rectangular neodymium magnets form a focused, directional magnetic field concentrated along the 20mm axis rather than distributed across a wider face.

The small neodymium magnets narrow 5mm width allows mounting in thin slots, narrow channel edges, and slim panel grooves where wider rectangular or round magnets would not physically fit. This rare earth magnet’s N35 grade and nickel coating match the specification standard of the square block and larger rectangular variants, offering a consistent rare-earth performance level in a much narrower form factor than the 20×10mm rectangle.

One practical trade-off: the 5mm width gives a 100mm² face area — half of the 20×10mm variant — producing proportionally lower face-pull holding force despite the same 20mm length. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices. This rectangular neodymium magnet is ideal for DIY projects, robotics applications and STEM models.
