This neodymium magnetic disc has a diameter of 5mm and a height of 2.5mm. It has a magnetic flux reading of 4841 Gauss and a pull force of 0.621 kilos. It is identified by the AMF magnet part number D-D5H2.5-N45.
Uses for our ferrite disc magnets:
Rare Earth magnets with handy dimensions such as these are a popular choice for savvy and experienced magnet users. There is nothing more frustrating than needing to measure and remeasure difficult to remember dimensions. Put the calculator away as this handy little disc magnet allows for you to work out the placement with ease, having the same diameter centre point as thickness. When additional strength is required these magnets can be used in combination to provide extra holding power. It is simply amazing how many modern day devices rely on the steady and permanent strength of strong Neodymium magnets. These super strong little round magnets can be found in all sorts of devices, from phones to highly specialised detection devices. Similarly, these magnets are just as popular with less technical users such as handicrafts people who are seeking a simple and refined means of attaching or displaying their creations.

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.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface
(of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to
the effects of gravity and the lack of friction between the surface and the shiny magnet.
