Neodymium Disc Magnet - 4.75mm x 1.5mm

Neodymium Rare Earth Disc Magnet Description:

This Neodymium Rare Earth Magnetic Disc has a diameter of 4.75mm and a height of 1.5mm. It has a magnetic flux reading of 3364 Gauss and a pull force of .290kg. Its part number is 20080.
This strong magnetic disc is made from Rare Earth magnetic material and has a nickel coating for corrosion resistance. Neodymium magnets are extremely strong, even in small sizes and provide for an effective yet compact magnet for a wide range of uses.


Uses for our Rare Earth Discs:

These petite Neodymium magnets are appropriate for attaching and holding items that are small and lightweights such as paper or cardboard. At just 1.5mm in thickness, these thin little magnets are incredibly versatile as they don’t add undue bulk or weight to items they are attached to.
They can be used as craft magnetic discs as they are a suitable size and strength for brochure and binder closure mechanisms. Small Rare Earth magnets such as these have become critical components in many electronic and medical devices. They can be found in all manner of objects from fridges, communication devices and computer hard drives to specialised scientific equipment.

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.

Needed some magnets for an art project.

Super happy with these magnets, they were the perfect size I needed, however, they are kind of fragile, and I broke a couple when they snapped back onto the stack of magnets I had on the table. D'OH.

Rare Earth Magnets

They worked fantastic! Using them on Games Workshop Dreadnoughts in the shoulder sockets so I can swap out weapon load-outs.
