Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 0.9 lbs of pull force under ideal conditions. |
| What is this magnet made of? |
NdFeB (Neodymium-Iron-Boron) rare earth material. |
| Is this stronger than N35 magnets? |
Yes. N52 is the highest standard neodymium grade and is significantly stronger than N35 magnets of the same size. |
| Can it be used outdoors? |
Yes. The Nickel-Copper-Nickel coating helps resist corrosion, although additional sealing is recommended for long-term outdoor or marine exposure. |
| What is it commonly used for? |
Crafts, thin magnetic closures, lightweight displays, embedded projects, office organization, classroom projects, models, and DIY builds. |
Product Overview
The N52 Neodymium Disc Magnet 1/4" x 1/32" is designed for applications that require strong magnetic performance in an ultra-thin profile. Measuring 1/4 inch in diameter and only 1/32 inch thick, this rare earth disc magnet offers excellent surface contact while remaining low-profile and easy to conceal in clean designs.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets provide maximum standard neodymium strength in a thin format. Their wide, flat shape makes them especially useful for holding notes, photos, lightweight materials, thin magnetic closures, crafts, models, and embedded installations where thickness must be kept to a minimum.
Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that helps protect against wear and corrosion while giving the magnet a smooth, polished finish. Supplied in a convenient 200-piece pack, these magnets are ideal for classrooms, offices, hobbyists, makers, manufacturers, and DIY projects that require consistent high-strength magnets in bulk.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a round permanent magnet made from an alloy of neodymium, iron, and boron (NdFeB). Neodymium magnets are the strongest commercially available permanent magnets and are widely used when compact size and high magnetic strength are important.
Disc magnets are especially useful for flush mounting, magnetic closures, displays, sensors, crafts, and compact assemblies because their flat shape provides strong surface contact while keeping the profile thin and easy to hide.
How Strong Is This Magnet?
This N52 neodymium disc magnet provides approximately 0.9 pounds of pull force under ideal conditions against a thick, flat steel surface. Although it is only 1/32 inch thick, the 1/4-inch diameter provides enough surface contact for reliable light-duty holding applications.
Its premium N52 grade gives it a noticeable performance advantage over lower-grade magnets of the same size, making it an excellent choice when you need the strongest available hold in an ultra-thin disc shape.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 0.9 pounds of pull force under ideal contact with a thick steel surface.
Is N52 stronger than N35?
Yes. N52 is the highest standard neodymium magnet grade and provides significantly more magnetic strength than N35 magnets of the same dimensions.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple-layer coating helps protect against moisture, oxidation, and everyday wear.
Can it be used outdoors?
Yes. For continuous outdoor, humid, or marine environments, additional sealing is recommended to maximize service life.
What direction is it magnetized?
This disc magnet is magnetized through its thickness, meaning the north and south poles are located on the two flat circular faces.
Do you offer bulk discounts?
Yes. Super Magnet Store offers competitive quantity pricing and wholesale discounts for manufacturers, distributors, schools, retailers, and OEM customers.
