Product Description
These ultra-thin N55 neodymium square block magnets deliver impressive magnetic strength in an extremely compact design. Made from premium rare earth alloy of neodymium, iron, and boron, each magnet provides 0.99 lb pull force while measuring only 1mm thick.
Each block features protective nickel-copper-nickel coating to prevent corrosion and ensure long-term performance. The exceptionally thin construction makes these magnets perfect for applications where space is limited, while the brittle ceramic-like material requires careful handling to prevent damage.
Important Safety Information
⚠️ WARNING: Handle with extreme caution - serious safety risks for children.
- CHOKING HAZARD: Keep away from children under 12 years old
- SWALLOWING DANGER: Can cause life-threatening internal injuries if swallowed
- Maintain minimum 6-inch distance from pacemakers and medical devices
- Prevent magnets from colliding forcefully to avoid dangerous shattering
- Keep away from electronic devices, credit cards, and magnetic storage media
- Use tweezers or magnetic pick-up tools for safe handling
- Store individually in non-magnetic containers or separated by thin spacers
Common Uses
Ideal for precision applications requiring strong, low-profile magnetic force including:
- Electronics assembly and circuit board mounting
- Model building and scale modeling projects
- Jewelry making and small craft applications
- Scientific research and laboratory procedures
- Magnetic closures for thin cases and covers
- DIY repairs in tight spaces and confined areas
- Educational demonstrations and classroom experiments
- Magnetic separation of fine metallic components
