3mm x 1.5mm (1/8" x 1/16") Neodymium Disc Magnet – N52 Grade

Key Features:

• Dimensions: 3mm diameter × 1.5mm thickness (Approx. 1/8" × 1/16")
• Magnet Grade: N52 
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for corrosion resistance
• Magnetization: Axially magnetized (Poles on the 3mm flat faces)
• Shape: Disc

Material Description:

Our 3x1.5mm N52 neodymium discs are among the most popular sizes for precision hobby work. These magnets provide a reliable magnetic snap for their size, making them ideal for small assemblies that require frequent opening and closing. They are the strongest permanent magnets available for this specific footprint.

Safety Tip: Neodymium magnets are brittle. Even at this small size, they can chip if allowed to jump together. Always slide them apart and handle with care to maintain the integrity of the plating.

Warnings and Safety Information:

• Choking Hazard: Very small and easily swallowed. Keep strictly away from children and pets.
• Medical Safety: Keep at a safe distance from pacemakers and other sensitive medical implants.
• Handling: Best handled with plastic or non-magnetic tweezers to prevent accidental "jumping" to metal tools.
• Not a toy. Intended for adult hobbyists, engineers, and industrial use.

Applications:

• Miniature model magnetizing (arms, heads, and weapons)
• Small magnetic closures for jewelry or boxes
• Magnetic sensors and reed switch triggers
• School science experiments and physics kits
• DIY home projects like fridge magnets or small spice racks
