Neodymium Cylinder Magnet - 3mm x 4mm

Magnetic Product Description:

This rare earth cylinder has a diameter of 3mm and a height of 4mm. It has a magnetic flux reading of 6180 Gauss. Its part number is 21062.


Uses for our rare earth cylinder magnets:

Small Neodymium cylinder magnets such as these are ideal for embedding into nonmagnetic surfaces to create simple and effective closing or holding mechanisms. Their small diameter makes them ideally suited to being inserted into a predrilled hole in timber, acrylic or any other material. Simply held in place with epoxy glue, these magnets can be used to produce a flush and seamless finish that is well suited to corporate logos, business brands, and signage. This magnet is also popular with the cabinet making industry who utilities its petite size recessed into wooden surfaces to create hidden closure mechanisms.

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.
