???? Mechanical Properties

???? Magnetic Properties

Magnetization direction: Magnetized through the thickness (2 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 broader and still focused magnetic flux distribution.

Approximate pull force: 600 – 800 grf (tested on a steel surface; stronger than the 1.5 mm version due to increased thickness).

⚙️ Applications

• Electronic circuit and sensor applications

• Mechanical prototyping and R&D projects

• Model making and hobby projects

• Medical and optical device components

• Magnetic holding or alignment systems

⚠️ Warnings and Usage Notes

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