Product Description

Neodymium Magnets 5/16 in x 1/8 in Disc N42

Neodymium Magnets 5/16 in x 1/8 in Disc N42 – Strong Rare Earth Magnets

Engineered for reliable strength in a compact form, these N42 neodymium disc magnets deliver consistent, high-performance magnetic force for a wide range of applications. With a 5/16-inch (0.3125”) diameter and 1/8-inch (0.125”) thickness, these rare earth magnets offer precise holding power while maintaining a low profile, making them ideal for crafts, sensors, small assemblies, and DIY projects.

Key Features:

• Strong N42 Grade: Stronger than N40, N38, and N35 grades, N42 magnets provide a BrMax of approximately 13,200 gauss for consistent magnetic performance in compact applications.
• Precision Disc Design: Measuring 0.3125 inches in diameter and 0.125 inches thick, these discs are small yet powerful, offering reliable holding force for tight spaces.
• Triple Coated for Durability: Nickel-Copper-Nickel triple-layer plating ensures excellent corrosion resistance and long-lasting durability.
• Magnetized Through Thickness: North and south poles are located on the flat surfaces for stable alignment and effective performance in your assemblies.
• Max Operating Temperature: 176°F (80°C): These magnets maintain full strength up to 80°C; avoid use near heat sources that could lead to demagnetization.
• Handle with Care – Brittle Material: Neodymium magnets are hard but brittle and may chip, crack, or shatter if allowed to snap together or collide with hard surfaces.

Frequently Asked Questions

Why choose N42 magnets for small projects?
N42 grade offers strong magnetic performance in a compact size, making it ideal for projects needing high holding force in tight spaces.

Are these magnets coated for protection?
Yes, they feature a Nickel-Copper-Nickel triple coating for corrosion resistance and long-term durability.

How are these magnets magnetized?
They are magnetized through the thickness, with north and south poles on the flat surfaces for stable alignment in your assemblies.

Can I use these magnets for crafts and hobby projects?
Absolutely. These compact yet strong magnets are perfect for crafts, DIY projects, closures, and small electronic assemblies.

Safety Note:

Neodymium magnets are extremely strong for their size. They can attract each other or metal objects suddenly, causing pinching or injury. They are also brittle and may chip or shatter if allowed to collide. Always handle with care, wear eye protection when handling large quantities, and keep away from children, pacemakers, and sensitive electronics.
