Magnetic Product Description:

This Rare Earth cylinder has a diameter of 4mm and a height of 5mm. It has a Copper (Cu) coating, an N38 Grade, a magnetic flux reading of 5849 Gauss, and a pull force of 0.553 kilograms. This product is identified by AMF Magnetics part number 21055C.

Uses for our Rare Earth Cylinder Magnets:

The Neodymium Cylinders are a great versatile product that is suited to many applications due to their small size but strong magnetic pull. These small Neodymium Cylinders specifically are 4mm in diameter and 5mm long, with a surprising pull force of just over 1 kilogram, considering their small size. n. This makes small Rare Earth cylinders perfect for applications where accuracy and precision is required, coupled with an elegant and sleek appearance. These small discs would often be used in display applications, arts and crafts, as well as within small motors used as a sensor mechanism. They are also known to provide accuracy and efficiency when used within electronic devices such as microphones and speakers.

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.
