???? Mechanical Properties

???? Magnetic Properties
Magnetization direction: Magnetized through thickness (2 mm).

Poles: Located on the front and back rectangular surfaces.

Magnetic field lines: Concentrated at the center of the surface.

The 20 × 20 mm surface area provides a balanced, wide, and focused magnetic flux distribution in a compact size.

Approximate pull force: 600 – 800 grf (tested on a steel surface; slightly lower than a 4 mm thick magnet due to reduced thickness).

⚙️ Applications

• Electronic circuit and sensor applications

• Mechanical prototyping and R&D projects

• Modeling and hobby projects

• Medical and optical device components

• Magnetic holders or alignment systems

⚠️ Warnings and Usage Notes
⚠️ Neodymium magnets are very brittle; they may crack under impact, shock, or pressure.
⚠️ Magnetic performance may decrease above 80 °C.
⚠️ Magnets can snap together or attract metal surfaces quickly — it is recommended to handle them with protective gloves.
