Neodymium Cylinder Magnet - 8mm x 8mm | N42
Magnetic Product Description:
This popular rare earth cylinder has a diameter of 8mm and a height of 8mm. It is an N42 grade rare earth magnet. It has a magnetic flux reading of 5902 Gauss and a pull force of kg. It is identified by the AMF magnet part number C-D8H8-N42.
Uses for our rare earth cylinder magnets:
This small Cylindrical Neodymium magnet is a popular size as it is well suited for embedding into the surface of building materials like wood, MDF or plastic acrylic sheeting. The 8mm thickness allows for plenty of clearance in standard thickness materials.
Rarely are the dimensions as straightforward as with this little beauty. You are afforded the unusual luxury of putting your calculator back in the drawer. There is surprisingly simple joy in using simple and elegant dimensions such as these. Where the diameter and thickness are one and the same.
Rare Earth magnets with these types of dimensions are always sought after, particularly with customers who may be new to magnets. There certainly is something comforting in using dimensions that are easy to navigate whilst getting the measure of a new material.
Reed switches are so commonplace that we forget they even exist. Furthermore we certainly don’t always contemplate just how they operate. Reed switches, as you may (or may not) remember from your schooling, is a switch that operates based on the proximity of a magnetic field. There are numerous products that utilise reed switches, including security devices and model railways and even the magical way your laptop knows to turn on when you open it up. These all rely on the constant, reliable and simple power of magnets.

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.
