Cylinder magnets

Only purchase these magnet because they are diametrically don't know how to use them because of the size? But it's a good start guys and girls can you get some diametrically ring magnets. 60mm,45mm OD thanks

Hi Darren,

Thank you for giving these diametrically magnetised cylinder magnets a try! We're pleased to hear you appreciate the diametric magnetisation feature - it really does make these 5.5mm x 20mm cylinders quite unique compared to standard axially magnetised magnets.

You're absolutely right that the compact 5.5mm diameter can make these little cylinders a bit tricky to work with initially. The diametric magnetisation means the north and south poles are on opposite sides of the cylinder rather than on the flat ends, which opens up some really interesting possibilities for rotating applications, sensors, and creative magnetic coupling projects once you get the hang of positioning them.

We really appreciate your product suggestion for diametrically magnetised ring magnets in those larger 60mm and 45mm outer diameters. Customer feedback like yours helps us understand what products would be valuable additions to our range, and we'll definitely take this into consideration for future product development.

Thanks again for choosing AMF Magnetics and for taking the time to share your thoughts!

No FAQ available

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.
