Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 0.8 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. N45 magnets provide noticeably greater magnetic strength than N35, N38, N40, and N42 magnets of the same size. |
| Can it be used outdoors? |
Yes. The Nickel-Copper-Nickel coating provides excellent corrosion resistance, although prolonged outdoor or marine exposure should include additional protection. |
| What is it commonly used for? |
Crafts, magnetic closures, lightweight displays, woodworking, electronics, models, organization, and DIY projects. |
Product Overview
The N45 Neodymium Disc Magnet 1/4" x 1/32" is designed for applications where a larger contact surface is needed while maintaining an ultra-thin profile. Measuring 1/4 inch in diameter and only 1/32 inch thick, this compact rare earth magnet delivers dependable holding power without adding noticeable thickness to your design.
Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these disc magnets provide stronger magnetic performance than standard grades while remaining lightweight and easy to integrate into projects. Their larger diameter increases contact area on flat surfaces, making them ideal for magnetic closures, displays, crafts, and embedded installations where appearance and space savings are equally important.
Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that helps resist corrosion while providing a smooth, polished finish. Packaged in a convenient 200-piece pack, these magnets are ideal for manufacturers, educators, hobbyists, crafters, and DIY enthusiasts who require a dependable supply of high-quality rare earth magnets.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a round permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Known for delivering exceptional magnetic strength relative to their size, neodymium disc magnets are widely used throughout electronics, manufacturing, woodworking, retail displays, education, and consumer products.
Their flat profile makes them especially well suited for applications requiring concealed installation, flush mounting, magnetic closures, and compact assemblies.
How Strong Is This Magnet?
Although only 1/32 inch thick, this N45 neodymium disc magnet generates approximately 0.8 pounds of pull force under ideal conditions against a thick, flat steel surface. The 1/4-inch diameter provides increased surface contact, allowing for reliable holding performance in lightweight applications.
Its premium N45 magnetic grade delivers greater magnetic energy than N42, N40, N38, and N35 magnets of identical dimensions, making it an excellent choice for projects where every bit of holding power matters.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 0.8 pounds of pull force under ideal contact with a thick steel surface.
Is N45 stronger than N35?
Yes. N45 offers noticeably greater magnetic strength than N35 magnets of the same dimensions, providing improved holding performance in compact applications.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple-layer coating provides excellent protection against moisture and everyday wear.
Can it be used outdoors?
Yes. For continuous outdoor or marine environments, an additional protective sealant is recommended to maximize service life.
What direction is it magnetized?
This 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 wholesale pricing and quantity discounts for manufacturers, distributors, schools, retailers, and OEM customers.
