Neodymium Block Magnet - 5mm x 1.7mm x 3mm | N50 | Magnetised Through 3mm

This high-strength Neodymium Block Magnet delivers exceptional magnetic performance in an ultra-compact form. Measuring 5mm long × 1.7mm wide × 3mm high, this magnet is ideal for precision applications where space is limited but strong holding power is essential.

Manufactured from Grade N50 neodymium, one of the strongest grades available, this block magnet produces a pull force of 0.385kg, despite weighing just 1 gram. With a surface gauss of approximately 6,440 gauss, it offers outstanding magnetic intensity for its size.

Unlike standard axially magnetised blocks, this magnet is side magnetised, making it particularly suitable for applications requiring lateral magnetic attraction, directional alignment, or specialised assemblies.

A durable Nickel-Copper-Nickel (NiCuNi) coating provides corrosion resistance and a smooth, professional finish, helping protect the magnet during handling and use.

Why Choose This N50 Side-Magnetised Block Magnet?

Neodymium magnets are the strongest permanent magnets available, and N50 grade offers maximum strength in minimal space. Combined with a side-magnetised orientation, this block magnet is ideal for specialised applications where traditional axial magnetisation won’t work.

This tiny Neodymium block magnet is diametrically magnetised and while it weighs about the same as a cotton ball, it delivers a powerful pull force of 385 grams. How is that even possible? The magic is in that Rare Earth - Neodymium. There’s plenty of fascinating science that will explain why Neodymium delivers such a powerful hold, but the maths tells the story - the magnetic energy value of Neodymium is about 18 times greater than the usual ferrite magnets by volume, and 12 times by mass. Job done.

The shape of these small block magnets makes them ideal for a huge range of applications, particularly in electronic devices, aeronautical, automotive, and mining.

Rare Earth magnets are also widely used in arts and crafts, textiles, leather crafts, costume and prop construction. Not bad for a magnet with the weight of a cotton ball.
