What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a permanent rare earth magnet made from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Neodymium magnets are widely used across manufacturing, engineering, robotics, electronics, medical devices, scientific equipment, and consumer products because of their exceptional magnetic strength and compact size.
Disc magnets provide excellent holding power while maintaining a low-profile design, making them ideal for magnetic closures, fixtures, sensors, woodworking, product assemblies, and countless custom applications.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1/2" x 3/16" N52 neodymium disc magnet provides approximately 12 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force can vary depending on several factors, including:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
For maximum performance, use this magnet against a clean, flat, thick steel surface.
Note: Pull force values are estimates based on ideal testing conditions. Actual performance should always be verified for your specific application.

Common Questions About This Magnet
Is N52 stronger than N42 magnets?
Yes. N52 provides significantly greater magnetic strength and energy than N42 magnets of the same size.
What is the pull force of this magnet?
This magnet provides approximately 12 pounds of pull force under ideal testing conditions.
Is this magnet coated?
Yes. It features a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating that helps protect against corrosion, oxidation, scratches, and everyday wear.
Can this magnet rust?
The protective coating greatly reduces corrosion. However, if the coating becomes damaged and the magnet is exposed to moisture, corrosion may occur over time.
