This small Rare Earth Disc comes in a popular compact size with a diameter of 4mm and a height of 2mm. It has a strong magnetic flux reading of 4667 Gauss and a pull force of 344g. For added protection and corrosion resistance, it has a nickel coating. This magnet neodymium disc is identified by part number 20082.
Uses for our Neodymium Rare Earth Disc Magnets:
Often used as craft magnetic discs, these small magnets are extremely strong for their size. This Neodymium high-grade N42 disc magnet has added holding strength to perfectly compliment this popular disc size. Their petite dimensions make them attractive magnets for home users and professionals alike. They have wide applications including in the design and production of sensors, actuators, electric motors and in packaging. They are also popular among artists, craftspeople and hobbyists. These craftspeople need a small magnet discreet enough to be incorporated into a design without being visible in the completed work.

Perfect for hanging prints!
I bought these with the magnart metal plates and they are strong enough to hold up my prints. Great quality!

Perfect!
I am so glad to have discovered a source of small magnets in Australia. I use them often in my sculptural work as they allow me to attach my lightweight sculptures to their bases in a way that allows for movement and change. This particular order of tiny 4mm x 2mm discs was for a large flock of 30 corellas made of recycled plastic wrap. I wanted to be able to fix them to their steel bases in a way that allowed them to move very slightly in the air currents to simulate a flock of corellas feeding on the ground. They are perfect!

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.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface
(of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to
the effects of gravity and the lack of friction between the surface and the shiny magnet.
