Thin but Strong: Why 15×2 mm N45 Disc Magnets Are Perfect for Paper, Displays & Creative Projects

Sometimes the best magnets are the ones you barely notice — until they hold everything firmly in place. The 15×2 mm neodymium disc magnet (N45) is a prime example: just 2 mm thick, but impressively strong for its size. This makes it ideal for uses where both discreet appearance and strong holding force are important.

Designed for Flat & Lightweight Applications

With a 15 mm diameter and only 2 mm thickness, this flat magnet fits perfectly into tight spaces, offering secure magnetic force without bulk. It’s especially useful for:

• Mounting paper, posters, and photos to magnetic walls or boards
• Creating display panels or point-of-sale presentations
• Model building, dioramas, or scale prototypes
• Crafting and packaging, such as closures for custom boxes or folders
• DIY LED panels or small housings, where hidden magnet attachment is needed

Thanks to its N45 magnet grade, this disc magnet delivers a holding force of up to 1.2–1.4 kg, depending on surface conditions – quite powerful for such a small and flat component.

Common Use Cases

🎨 Display & Framing Projects
Use 15×2 mm magnets behind posters or glass to hold artwork invisibly in place – no nails or clips needed.

🏗 Model & Tech Prototypes
Ideal for holding modular parts in place without glue or visible fasteners. Especially useful in electronics or architectural mock-ups.

📦 Packaging with a Premium Touch
Create magnetic closures for custom gift boxes, invitation folders, or sample kits. Clean look, satisfying “snap” effect.

🛠 DIY Solutions
From knife strips to tool boards, this magnet can be recessed into wood or plastic surfaces to create functional and attractive magnetic holders.

Tips for Best Results

• Use smooth, ferromagnetic surfaces like steel for maximum grip
• Combine with a thin steel plate as a counterpole when using a single magnet
• Avoid excessive lateral force – slide-resistance is lower than direct pull
