This rare earth disc has a pull force of 117 grams, a diameter of 3mm and a height of 1mm. It has a magnetic flux reading of 3798 Gauss.
This tiny Disc N45 Grade magnet is deceptively strong for its size and can hold many times its own weight. Because of that power-weight ratio, these magnets are important components for manufacturers of hi-tech electronic devices and sound and telecommunications equipment. Delicate holding requirements in jewellery design or model-making applications are also where these small discs rise to the occasion because they can attract and bond two surfaces together, inconspicuously and unobtrusively. Two discs can be glued in place or fitted into slots on each surface and configured so the opposing poles attract to each other, providing a simple pull-to-release type of attachment.
These tiny discs are very inexpensive and can provide a unique and repeatable fastening solution for many bespoke designs and for a multitude of purposes where they do their job brilliantly, without being seen.
WARNING!: ALL MAGNETIC PRODUCTS PRESENT A POTENTIAL SWALLOW HAZARD FOR CHILDREN AND PARENTAL SUPERVISION IS REQUIRED AT ALL TIMES.

Surface Treatment
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.
Range and Tolerance
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.
Magnetic Properties
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.
