Magnetic Product Description:

This Rare Earth disc has a diameter of 3mm and a height of 1mm. It has a magnetic flux reading of 3798 Gauss and a pull force of 117 grams. It is identified by the AMF magnet part number D-D3H1-N45.

Uses for our Rare Earth disc magnets:

These strong rare earth disc magnets are made from N45 grade Neodymium material. Small magnets such as these may be tiny in size however they are super strong relative to the less powerful magnetic materials such as ferrite or samarium cobalt. Permanent magnets come in a range of sizes however these petite little discs are unlikely to be suitable for heavy duty applications. They can be used by themselves or in multiples, allowing you to adjust how much magnetic power you need on a very subtle level by adding or subtracting magnetic material to adjust these strong magnets to your needs. Although you may not consider the hold of 117 grams to be extremely strong they really are when their miniature proportions are taken into account. These small magnets are craft makers dream as they strong magnets that can easily hide from view in delicate artworks. Neodymium disc magnets are key components in all sorts or modern products as they can be found in anything from electric motors to communication equipment. The neodymium magnetic material is nickel coated to provide good resistance to the corrosive effects of humid environments and the chrome finish can be quite useful for aesthetic applications.

Great product.

This size was right for its use. I have a knitted nativity scene that I wanted to set atop the upright freezer. These small magnets went into the feet of the sheep so they would stand up.

Tiny strong magnets

Purchased these 3mm magnets to replace lost magnets from a model kit. They have proven perfect for their purpose.

Very happy with all aspects if service and delivery.

No FAQ available

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.
