Neodymium Disc Magnet 4mm x 3mm N50
These Neodymium disc magnets are nickel-coated, have a pull force of 0.5352kg, weigh 3 grams and are 3mm in height with a diameter of 4mm. Gauss 6029, Grade N50, direction of magnetization through height.
It’s hard to imagine how a disc magnet weighing just 3 grams could deliver so much reliable, consistent strength. They’re the champions of the magnet world, punching above their weight when it comes to hold and power. Their nickel-coating adds another desirable quality to their impressive profile - they’re good looking as well. That strength and profile means these Neodymium disc magnets are the perfect partners for fashion designers, craftspeople, hobbyists and artists where a discreet magnet delivering reliable hold is required. Their reliability and small size mean they are also valued in industries such as communications, automotive, and electronics.
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.
