Magnetic Product Description:
This rare earth block magnet has a length of 20mm, a width of 10mm and a thickness of 4mm. It has a magnetic flux reading of 3087 and A pull force of 3.5 kilos against 3mm mild steel. It has the AMF magnet part number 22023. It has a centred 4mm countersunk hole with an 8mm head width.
Uses for our rare earth block magnets:
This Neodymium Block magnet has a Countersunk hole for easy attachment and is ideal for permanent fastening or temporary attachment as needed. It can be attached to any surface using a readily available flathead screw to create a magnetic field or to act as a holding device. You can create a simple metal recovery or debris cleaning tool by attaching the magnet to a wooden pole. Attachment of the magnet is quick and easily reversible when it is no longer needed. One or more of these magnets can be screwed into doors, cupboards, draws or cabinets and will act as a closing device by attracting any metal plate or object that approaches its magnetic field. They make an ideal tool-holding device when attached to the wall of your office or workshop. DO NOT OVER TIGHTEN THE ATTACHMENT SCREW TO AVOID CRACKING.

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.
