I recommend this product
Nice magnets.
I had expected a slightly larger reading on the surface of the magnet but these fulfill my needs for a small portable NMR system.

Magnetic Product Description:
This magnetic block is 100mm square and 25mm thick. It's one of the larger magnets that AMF Magnetics stocks and should be handled with extreme caution as it is very easy to injure oneself while using such a powerful magnet. It is classified under the AMF magnet part number 22000.
Uses for our rare earth block magnets:
These magnets are often used in the manufacturing of magnetic plates and for industrial and commercial applications.

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.
