Neodymium Block Magnet - 20mm x 6mm x 3mm | N52
Same Day Dispatch
Order before 1pm to qualify for same day dispatch.
This Neodymium block magnet weighs 5 grams and has a pull force of 3.2kg, Gauss 3895, Grade N52. It is 6mm in width, 20mm in length and 3mm in height. Its direction of magnetisation is through the height.
Neodymium Block magnets are ideal for applications needing a strong magnetic hold, but where the magnet must do the heavy lifting in a narrow space. The wide surface and narrow height of the Neodymium block magnet means it can bond securely with ferrous material but take up very little vertical space. The range of applications that those properties deliver are endless, from applications in manufacturing plants, classrooms, offices, household projects, framing, musical instruments, machinery and processing systems. Wherever you need to hold one surface against another in that confined space, this Neodymium magnet is your choice. Those low height dimensions mean it can be incorporated into products that have a low profile or slimline look with limited height space to offer. The shiny, nickel-coated exterior of this magnet makes it aesthetically appealing, as well as improving its resistance to corrosion, so even if it is visible on your project or application, this Neodymium magnet has all the charm and good looks for the job.

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.
