Mechanical Properties

Magnetic Properties
Magnetization direction: Along the thickness (5 mm) axis.

Poles are located on the rectangular surfaces (front and back).

Magnetic field lines concentrate at the center of the surface.

The 20 × 5 mm large surface area provides a dense and focused magnetic flux distribution.

Generates approximately 1,000 – 1,200 gf of surface pull force (tested on a steel surface).

⚙️ Applications

• Electronic circuit and sensor applications

• Mechanical prototyping and R&D studies

• Model making and hobby projects

• Medical and optical device components

• Used in magnetic holding or alignment systems

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