Magnetic Product Description:
This rare earth magnet has a length of 4mm, a width of 3mm and a thickness of 1.8mm. It has a magnetic grade of N50 and a NiCuNi (Nickel) coating. These Rare Earth Block Magnets are also known as Bar Magnets due to their rectangular block shape. This small but strong magnet uses a powerful Neodymium Permanent Magnet has a magnetic flux reading of 6698 and a pull force of 505 grams.
It is identified by the AMF magnet part number B-W3H1.8L4-N50
Uses for our rare earth block magnets:
AMF rare earth magnetic blocks are ideal for many applications and practical uses. These Neodymium block magnets are excellent for picking up nails & screws, as stud finders and for metal separation. They are often used to build electric generators, tool or knife holders and in metal detectors. Due to the size and dimensions of these Neodymium block magnets, they are also popular in electronics manufacturing, hobbies and crafts.
If you are in need of a greater pull-force or more heavy-duty, industrial style of block magnets see our other Neodymium Bar Magnets.
No FAQ available
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.
