Cylinder Neodymium Magnet sigel B3103 — 8×10 mm, nickel plated, holding power for 6 sheets

Neodymium cylinder magnet sigel B3103 measures 8 × 10 mm and has a nickel-plated finish. The compact magnet provides strong local magnetic attraction and is specified to hold up to six sheets of paper under typical conditions. Its small size and corrosion-resistant plating make it suitable for applications where a powerful, discrete magnetic fastener is needed for positioning, temporary mounting or organization in offices, workshops and craft environments.

Advantages

The nickel plating protects the neodymium core from oxidation and everyday wear while keeping the magnet compact and durable. High magnetic strength relative to its volume enables reliable holding of lightweight items without bulk. Its cylindrical shape allows stable contact on flat ferrous surfaces and easy alignment in small assemblies. The neutral finish integrates unobtrusively into many work and display contexts.

Suitable for

• Fastening and displaying up to six sheets of paper to metal surfaces
• Temporary mounting of lightweight signs, templates or patterns
• Positioning or holding small metal parts during assembly or craft work
• Desk organization, pinning notes or photos to metal boards

Key specifications

• Shape: Cylinder
• Material: Neodymium magnet with nickel plating
• Dimensions: 8 mm diameter × 10 mm height
• Rated holding capacity: holds up to approximately six sheets of standard paper on iron/steel surfaces
• Surface finish: Nickel-plated for corrosion resistance and smooth contact

How to use

Place the magnet directly onto a clean ferrous surface or use it to clamp paper and thin materials against metal. Ensure the contact area is flat and free from dust, paint flakes or non-metallic coatings that could reduce magnetic grip. For best results, align the magnet so its circular face sits flush against the metal surface. Avoid trapping fingers between strong magnets and metal parts.

Recommendations

Store magnets separately or with protective spacers to avoid accidental attraction and chipping. Keep away from electronic storage media and devices sensitive to magnetic fields. Use multiple magnets for heavier or larger items and test holding strength before long-term mounting.
