3mm x 3mm (1/8" x 1/8") Neodymium Cylinder Magnet – N52 Grade | The Ultimate Hobby Magnet

Key Features:

• Dimensions: 3mm diameter × 3mm thickness (Approx. 1/8" × 1/8")
• Magnet Grade: N52 – Maximum commercial energy product
• Pull Force: Approx. 0.75 LB
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for corrosion resistance
• Magnetization: Axially magnetized (Poles on the flat 3mm faces)
• Shape: Cylinder / Deep Disc

Material Description:

Our 3x3mm N52 cylinders are a favorite for high-end miniature gaming and precision engineering. The 1:1 ratio of diameter to height creates a very concentrated magnetic flux, making them feel much stronger than thinner magnets of the same diameter. They are ideal for applications requiring a deep, secure hold.

Handling Tip: At 3mm thick, these magnets are less likely to break than ultra-thin discs, but they are still brittle. Always slide magnets apart. If they snap together from a distance, the impact can still cause the plating to chip.

Warnings and Safety Information:

• Choking Hazard: Small size is dangerous for children and pets. Keep strictly in a secure container.
• Pinch Hazard: The N52 pull force at this thickness is strong enough to cause a sharp pinch. Handle with care.
• Medical Safety: Keep away from pacemakers and sensitive medical implants.
• Electronics: Avoid direct contact with magnetic storage media and mechanical watches.

Applications:

• Articulation for larger tabletop miniatures and action figures
• Magnetic sensors and industrial reed switches
• DIY magnetic tool organization and "hidden" cabinetry latches
• Advanced 3D printing projects (embedding magnets into parts)
• Scientific experiments and physics demonstrations
