Magnetic Product Description:
This neodymium magnetic disc has a diameter of 4mm and a height of 3mm. It has a magnetic flux reading of 6154 Gauss and a pull force of 0.558 kilos. It is identified by the AMF magnet part number D-D4H3-N52-DIA.
Uses for our Neodymium Disc Magnets:
Strong Neodymium magnetic material is incorporated into a huge array of tools and equipment, from the heavy duty down to the delicate. Tiny magnets such as this round magnet can be used as standalone magnets for attaching small items. Alternatively, they can be incorporated into more complex structures or devices, either as a single magnet or as a series to create a broader magnetic area.
This magnet is not only an extremely strong N52 grade magnet, it also has an unusual direction of magnetisation. Diametric magnetism means the North and South poles extend out from opposing sides of the round profile of the magnet. The poles are not present through the flat faces as is generally the case with disc magnets.
Diametrically magnetised magnets are normally used for more niche applications, perfect for components in specific types of equipment. They are not the most suitable magnets for people looking for a method of attachment.
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.
