Holds metal projects through my thick wooden bench. Stronger than I thought. A bit overkill but awesome.

Magnetic Product Description:
This block magnet has a length of 50mm, a width of 50mm and a thickness of 12.5 mm. It has a magnetic flux reading of 2581 Gauss and a pull force of 46.2 kilos against 5 mm mild steel.
Uses for our rare earth block magnets:
This square shaped magnet has a relatively low height profile and that combined with the large pole surface area make it ideal for clamping components together for a permanent, semi-permanent or reusable fixing point. It can bond with ferrous material or other magnets using the opposite pole. These dimensions are closely comparable with imperial 2-inch and 1/2 inch measurements. Pound for pound, Neodymium is the strongest magnetic material available today and that makes it a cutting-edge material for the ever-decreasing size of modern technologies where Telecommunications designers and Electric Motor manufacturers incorporate powerful yet small Neodymium magnets into their products to increase their functionality and desirability.
Magnets are found in all modern technologies from Robotics and Automation to Aerospace and Medical Science.

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.
