Neodymium Disc Magnet Description
Neodymium Disc Magnet - 3mm x 1mm | N50 | Gold Coating is a compact rare earth disc magnet measuring 3mm diameter x 1mm thick. Manufactured from N50-grade neodymium with a gold-plated finish, this magnet provides a magnetic flux density of 4,022 Gauss and a pull force of approximately 131 grams under ideal test conditions. It is suitable for refined displays, craft clasps, miniature model fixings, exhibition installations and specialised electronic componentry. This product is identified by AMF Magnetics product code D-D3H1-N50au.
Key Features
- Dimensions: 3mm diameter x 1mm thick
- Material: Neodymium
- Magnetic grade: N50
- Coating: Gold plated
- Pull force: Approximately 131g under ideal direct-contact test conditions
- Magnetisation direction: Through the 1mm thickness (axial)
- Product code: D-D3H1-N50au
Common Applications
This neodymium disc magnet is commonly used for:
- Small clasps for jewellery, craft projects and presentation packaging
- Museum, gallery and exhibition displays requiring a refined gold appearance
- Miniature model-making, signage and lightweight display fixings
- Specialised electrical, monitoring and security-device componentry
Choosing and Using This Product
This small gold-plated disc magnet is best suited to lightweight applications where a compact size and refined finish are important. It can be recessed, bonded into place with a suitable adhesive or paired with another magnet or steel surface. The gold coating offers useful corrosion resistance and electrical and thermal conductivity, but it should be protected from scratches, moisture and harsh environmental exposure. For the strongest result, install the magnet against a clean, flat and sufficiently thick ferromagnetic surface with minimal air gap.
The stated pull force is measured under ideal test conditions. Actual holding performance can be reduced by vertical loading, thin steel, coatings, surface gaps, uneven contact, vibration or elevated temperatures.
Safety and Handling
Due to its very small size, this magnet presents a serious swallowing hazard. Keep it strictly out of reach of children. Small neodymium magnets can attract suddenly, cause pinch injuries and damage nearby electronic or magnetic devices. Gold plating can be damaged by impact or abrasion; handle carefully and avoid exposing the magnet to corrosive or wet environments. A protective sealant may help extend coating life, although it can create an air gap and reduce holding force.
Frequently Asked Questions
What is this product best used for?
It is ideal for lightweight, compact applications such as jewellery clasps, miniature models, refined display installations and small electronic assemblies where a gold finish is preferred.
Will it hold a small display item or craft component?
It may hold lightweight items when it has full, flat contact with a suitably thick steel surface or a correctly matched magnet. The result depends on the item’s weight, orientation, surface finish and any air gap, so testing in the intended application is recommended.
Can this product be used outdoors?
Gold plating offers some corrosion resistance, but it is not intended to provide permanent protection in exposed outdoor environments. Moisture, salt air, scratches and damage to the coating can allow corrosion to develop. For outdoor use, protect the magnet with a suitable enclosure or sealant and inspect it regularly.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.
The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.
Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.
Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
