Neodymium Disc Magnet - 7mm x 3mm | N50

Magnetic Product Description:

This neodymium magnetic disc has a diameter of 7mm and a height of 3mm. It has a magnetic flux reading of 4717 Gauss and a pull force of 1.35 kilos. It is identified by the AMF magnet part number D-D7H3-N50.


Uses for our small rare earth disc magnets:

Small, round Neodymium disc magnets have many uses around the home, workspace and classroom. Their impressive holding power is also utilised in a wide range of industries where temporary fixing and attachment is preferable. Magnetic power and the adhesive properties it offers has become very influential in many modern product designs. Strong, round, rare earth magnets produce permanent magnetic hold and can add a practical, unique and attractive dimension to hobbies, craft, artwork and commercial products that can not be achieved with mechanical devices, tapes or glues.

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.
