Magnetic Product Description:

This popular rare earth cylinder has a diameter of 8mm and a height of 40mm. It is an N45 grade rare earth magnet. It has a magnetic flux reading of 6799 Gauss and a pull force of 3.18 kg. It is identified by the AMF magnet part number C-D8H40-N45.

Uses for our rare earth cylinder magnets:

Extracting high magnetic power from magnets with modest dimensions usually requires the employment of Rare Earth magnetic materials such as Neodymium or Samarium Cobalt. This AMF cylinder-shaped magnet, sometimes called a Rod Magnet, uses Neodymium material which is the strongest magnetic material of all. Small, round Neodymium magnets of a cylindrical shape have a deep and narrow field that can penetrate materials such as glass or thin timber to either detect metal on the other side or attach to it magnetically in a manner that doesn’t damage the surface in any way. Long, thin magnets, like this example with N45 Grade power, are used to detect metal fasteners, such as nails or screws, inside gyprock walls. Detecting these metal fasteners also identifies the location of the timber studs and noggins inside and indicates where it is safe to drill when hanging artwork or tv screens.

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.
