Neodymium Block Magnet - 9mm x 4.5mm x 7mm | N52 | Magnetised through 7mm width | North Marked

This compact yet exceptionally powerful Neodymium Block Magnet measures 9mm x 4.5mm x 7mm and is manufactured from premium N52 Grade Neodymium (NdFeB), one of the strongest commercially available permanent magnet materials. Despite its small size, this rare earth magnet delivers outstanding magnetic performance, making it ideal for precision applications where space is limited.

The magnet is magnetised through the 7mm width, with the North pole clearly marked for easy identification during assembly, testing, and magnetic orientation applications. Manufactured to a tolerance of ±0.05mm, this precision-engineered magnet is suitable for demanding industrial, electronic, scientific, and hobbyist projects.

Common Applications

These small N52 neodymium block magnets are widely used in applications where precise magnetic positioning and maximum magnetic strength are required in a compact form factor.

Popular uses include

• Electronic sensors and switches
• Robotics and automation systems
• Precision engineering projects
• Product prototyping and development
• Scientific experiments and laboratory equipment
• Magnetic closures and latches
• Miniature holding and locating systems
• Educational demonstrations

The clearly marked North face is particularly useful for projects requiring consistent magnetic orientation or multiple magnets arranged in specific pole configurations.

Why Choose N52 Neodymium Magnets?

N52 represents one of the highest-strength grades available in neodymium magnets, providing exceptional magnetic performance relative to size. This allows engineers, designers, and manufacturers to create smaller, lighter, and more efficient products while maintaining strong magnetic holding power.

For applications where every millimetre matters, N52 neodymium magnets offer a superior strength-to-size ratio compared to lower-grade magnets and alternative magnetic materials.

Important Handling Information

Neodymium magnets are extremely powerful and should be handled carefully. Avoid allowing magnets to snap together, as chipping or cracking may occur. Keep magnets away from sensitive electronic devices, magnetic storage media, and medical implants such as pacemakers.

Small magnets pose a serious swallowing hazard and should be kept out of reach of children at all times.
