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 extremely strong Rare Earth block magnet is 100mm long, 100mm wide and has a 25mm height. One of our largest and strongest magnets in stock, with a pull force of 294.20 kilograms. This magnet is identified by AMF Product Code 22000.
Uses for our Rare Earth block magnets:
These permanent magnets are often used in the manufacturing of magnetic plates and for industrial and commercial applications. They are one of our biggest magnets in size and have an extremely strong pull force of 294.20 kilograms. They are incredibly powerful and are not suitable for domestic use. The thickness or height dimension of this magnet (25mm) is often compatible with applications that require an Imperial equivalent of 1 inch (1") and a width and depth of 4 inches (4"). They are manufactured in grade N42 material which is one of our strongest grades.
PLEASE NOTE: These magnets are extremely dangerous and need to be handle with care.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.
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.
