Product Overview

Designed for applications where space is limited, these 1/2" x 1/32" N42 Neodymium Disc Magnets provide dependable magnetic performance in an ultra-thin profile. The larger 1/2-inch diameter creates excellent surface contact for reliable holding power, while the slim 1/32-inch thickness allows the magnet to sit nearly flush when embedded into wood, plastic, paper products, or other materials.

Manufactured from premium N42 grade rare earth neodymium, these magnets offer an excellent balance of strength, versatility, and ease of use. They are ideal for lightweight holding applications, magnetic closures, crafts, models, displays, and precision assemblies where a discreet installation is desired.

Each magnet is finished with a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent protection against corrosion, scratches, and chipping while maintaining a smooth, polished appearance.

What Is a Neodymium Disc Magnet?

A neodymium disc magnet is a circular permanent magnet made from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Disc magnets are magnetized through their thickness, placing the north and south poles on the two flat circular faces to maximize holding power.

Ultra-thin disc magnets are especially useful where minimal thickness is required without sacrificing magnetic performance, making them popular for crafts, displays, packaging, woodworking, electronics, and educational projects.

How Strong Is This Magnet?

This 1/2" x 1/32" N42 disc magnet provides approximately 1.6 pounds of pull force under ideal conditions using a thick, clean steel surface.

Although extremely thin, the larger diameter helps maximize contact area, allowing the magnet to provide reliable holding power while remaining nearly flush when installed.

Nickel-Copper-Nickel vs. Epoxy Coating

Every magnet features a Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, offering significantly greater durability than standard epoxy-coated magnets.

Nickel-Copper-Nickel Triple Coating Benefits

  • Superior scratch resistance
  • Better resistance to chipping and cracking
  • Enhanced corrosion protection
  • Smooth, polished metallic finish
  • Longer-lasting durability during everyday use

Epoxy Single-Layer Coating

Epoxy coatings consist of a thin plastic layer that can wear more quickly with repeated handling. Even minor scratches may compromise the protective surface over time. Nickel-Copper-Nickel plating provides improved resistance to mechanical wear while maintaining an attractive metallic finish.

Common Questions About This Magnet

What is the pull force?

This magnet provides approximately 1.6 pounds of pull force under ideal conditions.

Is N42 stronger than N35?

Yes. N42 offers noticeably greater magnetic strength than N35 magnets of the same dimensions.

Can it rust?

Like all neodymium magnets, it contains iron and can corrode if the protective coating becomes damaged or if exposed to moisture for extended periods.

Can it be used outdoors?

Yes. However, for long-term outdoor or marine applications, additional sealing is recommended.

What direction is it magnetized?

This magnet is magnetized through its thickness, with the north and south poles located on the two flat circular faces.
