Product Overview

These 3/4" x 1/10" N45 Neodymium Disc Magnets offer an excellent combination of strong holding power and a slim profile. The 3/4-inch diameter provides a generous contact surface for secure attachment, while the 1/10-inch thickness increases magnetic strength over thinner disc magnets without adding excessive bulk.

Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver stronger magnetic performance than N42, N40, N38, and N35 grades. They are ideal for woodworking, magnetic closures, product assemblies, displays, engineering applications, and custom DIY projects where reliable magnetic performance is essential.

Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished metallic finish.

What Is a Neodymium Disc Magnet?

A neodymium disc magnet is a permanent magnet manufactured from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Disc magnets provide exceptional magnetic force in a compact, low-profile shape, making them one of the most versatile magnet styles available.

These magnets are magnetized through their thickness, placing the north and south poles on the two flat circular faces. This design makes them ideal for magnetic closures, woodworking, fixtures, displays, electronics, robotics, product assemblies, and industrial applications.

Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.

How Strong Is This Magnet?

This 3/4" x 1/10" N45 disc magnet provides over 7.7 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.

Actual holding force depends on several factors, including:

  • Surface material
  • Steel thickness
  • Contact area
  • Air gap
  • Mounting method
  • Environmental conditions

For maximum holding performance, use this magnet against a clean, flat, thick steel surface.

Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified in your specific application.

Common Questions About This Magnet

What is the pull force?

This magnet provides over 7.7 pounds of pull force under ideal testing conditions.

Is N45 stronger than N42 magnets?

Yes. N45 delivers greater magnetic strength and holding power than N42 magnets of the same size.

Can this magnet rust?

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

Can it be used outdoors?

Yes. 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.
