Product Description
Neodymium Magnets N50 1/2 in x 1/4 in Rare Earth Disc
N50 Magnets Disc 1/2 in x 1/4 in – High-Power Rare Earth Magnet for Compact Precision Applications
Engineered for precision and reliable holding power in a compact size, this N50 neodymium disc magnet (0.5” diameter x 0.25” thick) offers a high-strength solution for projects requiring strong magnetic force in limited spaces. Rated for temperatures up to 80°C (176°F), it maintains reliable performance in most indoor applications.
Note: Neodymium magnets are brittle by nature. Avoid impact or sudden collisions with hard surfaces to prevent chipping or cracking
Key Features:
- N50 High-Power Grade: Stronger than N48, N45, and lower grades, delivering a BrMax of 14,500 gauss for maximum performance in small form factors.
- Pull Force: Approximate Pull Force of 17 lbs under ideal conditions (flat, clean, thick steel surface). Actual performance may vary with uneven or non-ferrous mounting surfaces.
- Compact Disc Design: The 0.5-inch diameter and 0.25-inch thickness make it ideal for electronic, hobbyist, and engineering applications where space efficiency is critical.
- Triple Layer Coating: Triple Layer Coating: Nickel-Copper-Nickel plating ensures long-term corrosion resistance, but the magnet remains brittle—handle with care to avoid chipping.
- Magnetized Through Thickness: North and south poles are on the flat ends for secure, predictable contact and alignment.
Applications
This N50 neodymium magnet disc is perfect for:
- DIY electronics and sensor projects
- Hobby and craft magnet applications
- Compact magnetic closures and latches
- Educational science kits and demonstrations
- Robotics and small mechanical assemblies

Frequently Asked Questions (FAQ)
Is the N50 grade significantly stronger than N48 or N45?
Yes, N50 offers higher magnetic strength in the same dimensions, making it ideal for applications requiring maximum force in a compact design.
Can this be used for electronics and small projects?
Absolutely. Its small size and strong pull force make it excellent for sensor mounting, hobby electronics, and prototyping.
Is it durable for repeated use?
While the triple-layer coating protects against corrosion, the magnet itself is brittle and may chip or crack if dropped or allowed to snap together with another magnet. Always handle with care, especially during installation.
What is the maximum operating temperature? This N50 magnet is rated for continuous use up to 80°C (176°F). Exposure to higher temperatures may result in a permanent loss of magnetic strength.
Will I always get 17 lbs of pull force?
The stated pull force is based on ideal lab conditions using thick, smooth steel. Actual holding strength may be reduced on curved, textured, thin, or painted surfaces.
