Super strong magnets, great price and service
These magnets work perfectly in a DIY magnetic knife block.
Shipped really fast to New Zealand too, cheers!

Magnetic Product Description:
This block magnet uses the AMF magnet part number 22019. It's 25mm in length, 12.5mm wide with a thickness of 3.5mm. It has a magnetic flux reading of 2299 Gauss and a pull force of 4.7 kilos against 5mm mild steel.
Uses for our rare earth block magnets:
We supply this Neodymium Block to engine manufacturers, signmakers and design companies. Also very handy for hanging signs. artwork or graphic displays.You can hang Christmas decorations, or anything else from industrial or office ceilings by attaching to the thin metal frame supporting the polystyrene ceiling panels. Of course, it will attach to filing cabinets and steel door frames just as easily!

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.
