Magnetic Product Description:
This rare earth block magnet has a length of 40mm, a width of 10mm and a thickness of 4mm. It has the AMF magnet part number 22008. It has a centred 4mm countersunk hole with an 8mm head width.
Please note: this magnet is susceptible to breaking or cracking if attachment screws are over-tightened.
Uses for our rare earth block magnets:
People are excited by the nature of magnetic engagement. However, it is the simplicity of breaking the magnetic bond that makes magnets so useful.
Once an individual magnet’s pull force or holding strength has been exceeded, the magnetic bond will cease. This characteristic allows designers and tradespeople to choose a magnet as much for its release threshold as for its holding ability. This magnetic method has considerable advantages over bolts, rivets, screws and glues, who are now considered old-fashioned fastening methods. Products suspended with magnetic hold in retail stores highlight the product’s availability and exclusivity. The secret or hidden fixing method adds to the allure of a product, especially for luxury goods.
This very practical countersunk Neodymium block magnet is ideal for fastening to non-metallic surfaces and is popular with carpenters, sheet metal fabricators, aluminium and glazing suppliers and door furniture outlets. It enables any surface to become a magnetic surface and attract or hold metal items securely. This Countersunk magnet allows for projects where the magnet needs to be fixed to a wooden or other type of surface neatly and with no protruding parts above the surface of the magnet. It is often applied to sliding doors or cabinets in combination with a metal plate to act as a simple closing device. A self-tapping screw with a slotted or Phillips head will secure the magnet in place.

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.
