Magnetic Product Description:

This neodymium magnetic disc has a diameter of 3mm and a height of 2.5mm. It has a pull force of 0.267 kilos. It is identified by the AMF magnet part number D-D3H2.5-N45.

Uses for our Rare Earth disc magnets:

Rare earth magnets come in all sorts of sizes, shapes and grades. From petite little magnets through to heavy-duty magnets, Neodymium is the magnetic material of choice. Renowned for its powerful magnetic properties, Neodymium is the strongest type of permanent magnet. It has allowed for huge technological developments across a wide range of industries that have taken advantage of the powerful reliable magnetic hold this material provides.

Tiny round magnets such as this have an incredibly diverse range of applications. They are commonly incorporated into all sorts of electronic equipment like phones, speakers, sensors, alarms and myriads more. They are also popular with jewellery makers, craftspeople or just your garden variety home tinkerer. Able to impart a surprisingly strong magnetic field, these little circle magnets are always in high demand.

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.
