???? Mechanical Properties

???? Magnetic Properties

• Magnetization Direction: Magnetized through the thickness (1.5 mm).

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

• Magnetic Field Lines: Concentrated near the center of the surface.

• The 20 × 8 mm surface area provides a compact yet broad and focused magnetic flux distribution.

• Approximate Pull Force: 400 – 600 grf (tested on steel surface; lower than 3 mm thick models due to reduced thickness).

⚙️ Applications

• Electronic circuits and sensor systems

• Mechanical prototyping and R&D projects

• Model making and hobby applications

• Medical and optical device components

• Magnetic holding or alignment systems

⚠️ Warnings and Usage Notes

⚠️ Neodymium magnets are very brittle; they can crack or chip under impact, collision, or compression.
⚠️ Magnetic performance decreases above 80 °C.
⚠️ Magnets can snap together or strike metal surfaces quickly — use protective gloves during handling.
