Neodymium Block - 25mm x 3mm x 9mm (Axially magnetised thru 3mm width)
Product code: 22021
Neodymium Block - 25mm x 3mm x 9mm (Axially magnetised thru 3mm width)
Magnetic Product Description:
This rectangular rare earth magnet has a length of 25mm, a width of 3mm and a thickness of 9mm. It has a magnetic flux reading of f5763 and a pull force against 5mm steel of 3.2 kilos. It is identified by the AMF magnet part number 22021. It is magnetized through the9mm thickness.
Uses for our rare earth block magnets:
This magnet has been used by local film production facilities when positioning props on film sets and also when adhering items to clothing. It is a compact size which can be used in a lot of applications. Ideal for the hobby market.
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.
