Great magnets
Pay attention to the kg ratings as these magnets are as strong as they state.

Magnetic Product Description:
This rare earth disc has a diameter of 22mm and a height of 15mm. It is identified by the AMF magnets part number 20010A.
Uses for our rare earth disc magnets:
The Disc shape has inherent benefits in that while retaining very strong holding power, the top and bottom pole surfaces can be dislodged when sheer force is applied. Removal of the magnet can be repeated by breaking the adhesive bond with a simple sideways motion onto a non-magnetic surface. This characteristic is demonstrated when used to locate metal objects that are hidden inside a stud wall. Sliding the magnet across the wall until it attracts to a nail or screw in the timber stud allows the user to identify the desired affixing area. Now you can hang your valuable Artwork or Flatscreen TV, with confidence! In addition, N42 Grade magnets have higher magnetic energy ie; pull force, than standard magnets.

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.
