This rectangular block magnet measures 40mm in length, 15mm in width, and 8mm in height. It features a pull force of 19.98 kg and a magnetic flux density of 2767, coated with durable Nickel. It is catalogued under AMF Part Number 22007.
This Neodymium Block magnet offers a moderate strength level within the AMF product lineup. Measuring 40mm x 15mm x 8mm, it delivers a notable pull force of 19.98kg. Its high N52 magnetic grade ensures superior power compared to similarly sized Rare Earth magnets with lower grades.
Neodymium block magnets like these are commonly employed in industrial settings, often serving as virtual ‘torque limiters.’ In this role, the magnets act as safety devices that yield under excessive load or stress, helping to protect machinery from damage and reduce the risk of injury.
These magnets are also suitable for various applications that demand a moderate pull force, including knife holders, water purification, secure holding, and a range of engineering and industrial tasks.
Yes, you can. We suggest the maximum air gap is 2mm only (thickness of the wood between the magnet and knife). Your project requires a trial-and-error approach depending on the very light weight of the objects. It depends on the thickness of timber, the weight of the item you wish to attach, quality of steel to name a few variables. Also note that vertically placed magnets/knives will lose 70% of their pull force. If you are attaching different tools, some heavier than others, you may have to increase the pull force (size, diameter/thickness) of the magnets.

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.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
