10×10×2mm Square Neodymium Magnet for DIY

The 10×10×2mm Square Neodymium Magnet for DIY permanent magnet measuring, silver-finish nickel coating, weighing 10 grams, designed for DIY, acoustic, and electronics builds. This Neodymium Magnet’s silver appearance comes from a nickel-copper-nickel tri-layer protective coating applied over the NdFeB core — raw neodymium-iron-boron alloy corrodes rapidly in humid or exposed environments, and this plating protects the magnetic core from oxidation degradation that would otherwise reduce the magnet’s holding strength over time.

The Square Neodymium Magnet’s 10×10×2mm thin block form is stackable — placing two or more of these magnets face-to-face along their 2mm thickness axis combines their magnetic circuits and increases total pull force proportionally, allowing builders to scale the effective holding force by stacking multiple units rather than sourcing a single thicker magnet. This magnet bar block configuration also works in the opposite direction — separating the two magnetic poles by increasing the air gap (moving the magnet away from the target surface) reduces force rapidly, which is useful in reed switch triggering applications where a specific trigger distance needs to be set.

this neodymium block magnet’s N35 grade loses magnetization progressively above approximately 80°C — placing this magnet near motor coils, high-current connections, or other heat-generating electronics in enclosed builds risks partial demagnetization over time. Available from StemVolt, this unit is suitable for engineers working on protected magnetic assembly builds and practical n35 magnet DIY electronics projects.
