Magnetic Product Description:
This Neodymium Block Magnet has a Length (L) of 25mm, a Width (W) of 12.5mm, a Height (H) of 3.5mm, and has a 4mm diameter hole. It is an N42 grade magnet and is axillary magnetized. This product is identified by AMF Magnetics product code 22019A.
Uses for our rare earth block magnets:
These Neodymium Block Magnets are popular with signmakers and design companies. Their low profile makes them ideal for applications that require a robust holding capacity as they have a good resistance to sheering forces. Perfect for hanging signs and displays from just about any ferrous metal surface; you can even make use of the thin metal frame supporting office ceiling panels! The large rectangular surface of the polarised faces makes this magnet ideal for applications that require a large area to attach a non-magnetic object to.

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.
