Neodymium Disc Magnets
Small, round Neodymium Disc magnets have become important components in most modern electronic devices while also remaining one of the most popular magnets for everyday holding and attachment purposes. All rare earth magnets produce excellent magnetic energy for their size and this leads to their use in delicate artistic applications, to generate power in small DC electric motors,and as vital components in sensitive medical and industrial monitoring equipment. Round, symmetrical disc-shaped permanent magnets such as this N45 Grade Neodymium disc also project even and constant magnetic fields that are ideal for responding to electromagnetic impulses and are widely used to convert sound vibrations in microphones and guitar pick-ups to electrical signals. These signals can then be digitally recorded or amplified. Disc shaped magnets are inherently flat and take up very little vertical space, so Neodymium discs can be glued to a flat surface with little visual impact or interruption to existing processes or appearances. This type of attachment avoids recessing the magnet into another material which can be difficult and time consuming and is the common practise for magnets with taller height dimensions.
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.
