Neodymium Cylinder Magnet - 25mm x 25mm | N52

Magnetic Product Description:

This popular rare earth cylinder has a diameter of 25mm and a height of 25mm. It is an N52 grade rare earth magnet. It has a magnetic flux reading of 5635 Gauss and a pull force of 32kg.  It is identified by the AMF magnet part number 21008/52. LIMITED STOCK.


Uses for our rare earth cylinder magnets:

Neodymium Cylinder Magnets are often used in industrial applications such as engineering firms and construction sites. Their high strength and small size is a great benefit as they can hold heavy weight without taking up too much space. This Neodymium Cylinder is 25mm in diameter and 25mm in height and has a magnetic grade of N52 which is responsible for its higher than usual strength of 32kg. Other Neodymium cylinders of this size in a lower grade would not have a pull force as impressive as this one. This incredible magnet combines the benefits of small discrete size with a strong and powerful magnetic pull. Ideal for use within high-performance crafts such as airplanes, motor vehicles, marine crafts, and drones. Their versatility allows them to be used in a variety of applications, not limited to the examples above.

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.
