Magnetic Product Description:
This rare earth disc has a diameter of 7mm and a height of 3mm. It has a magnetic flux reading of 4100 Gauss and a pull force of 1.04kg. It is identified by the AMF magnet part number 20068.
Uses for our rare earth disc magnets:
Companies using state of the art laser guided design and fabrication methods often use this small but strong 7mmx3mm Rare Earth magnet to construct bespoke product displays and oversize product replicas that require simple, efficient assembly and give an appearance of permanence while in fact, being temporary. The display items need to meet a client’s exact specifications based on the type of products to be displayed, or the size of the particular space that they are required to fit.
Rare Earth magnets are reliable, reusable and easily removable, allowing the designers to make adjustments through the design and build stages without damaging surfaces in the process. Once constructed, the display sections can be delivered to site in a flat pack format and joined together in situ and adjustments made if necessary to meet site issues or changing circumstances.The replacement of screws by magnets in the assembly and dismantling phase reduces skill requirements, labour costs and greatly extends the life of the display by eliminating the need for drilling. These magnets find widespread acceptance in businesses reliant on visual communication to attract potential customers.

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.
