Order before 1pm to qualify for same day dispatch.
This Nickel-coated Neodymium block magnet weighs 0,223 gram, has a pull force of 0.3990kg and is 1.77mm long, 5mm wide and 3.5mm high. Gauss 6609, Grade N50 and is side magnetised.
Note: Diametrically Magnetised. These nickel-coated Neodymium disc magnets may be tiny, but don’t let their size fool you. They punch way above their weight in terms of strength and pull force. These Rare Earth magnets may weigh about the same as a paper clip and have a width approximately equal to a pencil eraser, but that doesn’t mean they’re not up to the job.
Their sleek finish and versatile shape mean they are ideal for an almost limitless range of applications in any area where two surfaces need to be held together. It’s a case of using your imagination. These magnets are a vital component in the fields of art, fashion design, electronics, retail display, signage, construction, costume making, model-making, avionics, audio visuals and more.

Surface Treatment

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.
Range and Tolerance

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.
Magnetic Properties

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.
