Very strong magnet
I use my magnet on my manual press to hold leather punch tools to punch holes in my leather project much easier then using a hammer.

Magnetic Product Description:
This magnet has a length and width of 25mm with a height of 5mms. It has a magnetic flux of 2132 Gauss and a pull force of 10.3 kilos against 5mm mild steel. It uses the AMF magnet part number 22012.
Uses for our rare earth block magnets:
These magnets will instinctively jump in the direction of metallic material they are attracted to, and to each other and so need to be treated with caution. Designers and tradespeople are able to choose an individual magnet’s predictable instinct to attract or repel for specific purposes. Designers and their clients have a growing need for devices that are easy to service, clean and dismantle for transportation or storage and this small but strong Neodymium block help make this achievable.
Magnets bond to metal, or each other, without penetrating the host materials and have little or no effect on the structural integrity of the surface they adhere to. Nails, pins, rivets, screws and bolts, by nature and design, pierce surfaces. Glues deface plastics when unfastened. Penetration weakens or fatigues plastics at the point of entry and facilitates moisture access as well as compromising the uniformity and integral strength of plastic.
This popular magnet is used by shopfitters, material handling companies and is continually purchased by a V8 Supercar race engineering team who require the unique hold, and instant removal qualities that magnets of the correct size and strength provide.

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.
