Magnetic Product Description:

This neodymium cylinder magnet has a diameter of 6mm and a height of 25mm. It has a magnetic flux reading of 6255 Gauss and a pull force against 3mm mild steel of 1.5kg. It is identified as part number 21039.

Uses for our rare earth cylinder magnets:

The more Neodymium material between the North and South pole surfaces, the greater the magnetic force generated by the magnet. Available in N42 Grade Neodymium, these Neodymium Cylinders have deeply penetrative but narrow fields and can be matched to suit a particular circumstance with particular strength requirements. Unlike Discs, these tall, cylinder-shaped magnets are easy to dislodge because of their small pole surface area and elongated height dimension. Their cylindrical shape also produces a field that is deep and can penetrate through other surfaces to detect metallic objects or magnetic fields that are otherwise invisible to the eye. Small cylinders like this are found in detection devices and security systems that rely on their compact size and their ability to produce a far-reaching, permanent magnetic field. Slim magnets like these cylinders make good markers or position indicators on whiteboards, maps or site-plans in the office or any educational environment.

Neodymium Cylinder Magnet - 6mm x 25mm (21039)

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.

used for a DIY guitar pickup, perfect size!

Bought the 25mm one to cut in half to use in 2 pick ups made from bobbins and coil wire. Fit the bobbin perfectly and worked an absolute treat! Prompt delivery too.
