Mechanical Properties

 Magnetic Properties

• Magnetization Direction: Magnetized through thickness (3 mm).

• Poles: Located on the front and back rectangular faces.

• Magnetic Field Lines: Concentrated at the center, denser near the edges.

• 40 × 10 mm surface area provides alignment advantages in linear applications due to its elongated form factor.

• Approximate Pull Force: 3 – 4 kgf (tested on a steel surface).

⚙️ Applications

• Magnetic holding and fastening systems

• Industrial sensor and motor applications

• Mechanical prototyping and engineering projects

• Model making, CNC, and R&D applications

• Strong magnetic coupling or alignment systems

⚠️ Warnings and Usage Notes

⚠️ Neodymium magnets are very strong but brittle; they may crack or chip under impact, pressure, or collision.
⚠️ Magnetic performance may decrease above 80 °C.
⚠️ Magnets can snap together or to metal surfaces rapidly — wear protective gloves when handling.
⚠️ Keep away from children.
