100 Pack of Neodymium Block Magnets | 5mm x 1.7mm x 3mm | N50 | Magnetised through 3mm

This 100 pack of Neodymium Block Magnets pack exceptional magnetic performance into a remarkably small footprint. Measuring just 5mm x 1.7mm x 3mm, these magnets are ideal for applications requiring maximum strength in minimal space, making them a favourite for precision engineering, electronics, modelling, and advanced DIY projects.

Manufactured from high-grade N50 neodymium, these magnets offer significantly higher strength than standard grades, delivering a theoretical holding force of up to 0.385kg per magnet. Each magnet is magnetised through the height (3mm), through the small 5mm × 1.7mm face, ensuring efficient and consistent magnetic performance across compact assemblies.

A durable Nickel (Ni) coating provides corrosion resistance and a smooth, professional finish, helping protect the magnets during handling and installation.
