Neodymium Disc Magnet - 4mm x 2mm | N50

Magnetic Product Description:

This neodymium magnetic disc has a diameter of 4mm and a height of 2mm. It has a magnetic flux reading of 5124 Gauss and a pull force of 0.403 kilos. It is identified by the AMF magnet part number D-D4H2-N50.


Uses for our Rare Earth Disc Magnets:

The North and South magnetic poles of this strong N50 grade Neodymium disc magnet appear on the opposing flat circular surfaces. In other words, the magnetic field passes through the 2mm thickness dimension. These negative and positive poles will attach to a metal surface. They also attract magnets with the opposite pole present or repel a magnet with the same pole present. The intensified magnetic field produced by Neodymium material is superior to all other permanent magnets and compensates for the diminutive dimensions of small magnets such as this.
Disc magnets of any size or strength are useful for applications where height is restricted or when they are required to operate in confined spaces. Flat, round magnets are easily concealed beneath the surface of a product or inside the lining of a material or garment. Rare Earth magnets can be used to create a magnetic bond between two surfaces that are not metallic. They are easily glued to each surface with opposing poles exposed, forming a bond that is both permanent and removable that can replace the need for old fashioned fixture systems such as screws and nails. When creating a bond with steel surfaces, only one magnet is required.

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.
