Neodymium Block Magnet - 50.8mm x 25.4mm x 6.35mm
Magnetic Product Description:
This rectangular block magnet has a length of 50.8mm, a width of 25.4mm and a height of 6.35mm. It has a pull force of 13.58 kgs against 10 mm mild steel and a magnetic flux of 2003 with a Nickel coating and a grade of N35.
Uses for our powerful rare earth block magnets:
RIC is an acronym of the qualities permanent neodymium blocks bring to the table. Renew, (renew function or task), instinct (intuitive engagement and disengagement) and compatibility, (able to be used in combination with any and all materials). RIC.
The first of these qualities of magnetic power is an ability to renew. Magnets can renew their function of fastening, holding, releasing or regulating, over and over again, as if for the first time. Further, this renewing of purpose or re-application of the task is applied with no fatigue or penalty to components or materials subject to magnetic force. Magnetic fastening and its renewable engagement make the product much easier to clean and service, increasing desirability and longevity.
Block magnets second loved quality is an instinct to fasten or bond. Block magnets will jump, if allowed, at attracted objects. The maker of a product chooses a magnet for a particular function based on the size, strength and direction of pull or push force required.
Block magnets instinct to bond and release at threshold pressure, or quit the grip force defines them as virtual ‘torque limiters’ or an ‘overload clutch’. These failsafe mechanisms are installed to protect machinery or products in crash stops and jams, protecting the device from serious failure. Once the excessive force event has been addressed, the magnetic instinct is to re-engage, to its original position, as if for the first time, renewed.
Neodymium blocks are compatible, like peas in a pod, no matter what the material, but especially plastics.
This is a great all-purpose rectangular magnet which can be used when a reasonable amount of force is required. Applications include water purification, commercial door holders and for general engineering and industrial uses.

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.
