Neodymium Disc Magnet - 6mm x 3mm | North Marked

Neodymium Rare Earth Disc Magnet Description:

This Disc Magnet uses powerful Rare Earth magnetic material. This allows for a strong magnetic force for it’s compact size. This disc magnet also has its North Pole marked for easy identification.
This rare earth disc has a diameter of 6mm and a height of 3mm. It has a magnetic flux reading of 4455 Gauss and a pull force of 800 grams. It is identified by the AMF magnet part number 20071A.


Uses for our Neodymium Disc Magnets:

This Neodymium Rare Earth Magnetic Disc has a small mark on one side delineating the North Polarity. This demarcation allows for easy and quick identification of the magnetic aspect of each magnet when using multiple together. The North Pole marking makes handling and storing the magnets effortless.
This marking lessens the chance of magnets being damaged in handling when they accidentally snap back together with force. Furthermore, it provides increased safety for those handling magnets by reducing the risk of pinching skin as the magnets pull together unexpectedly. The user can both visually see the marking and feel the mark tactilely.
For applications such as repetitive manufacturing, this marking is essential to prevent accidental inversion of the poles. Incorrect positioning of magnets could cause large-scale manufacturing to be brought to a standstill or event product malfunction post production.

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.

like poles repelling property

I am exploring the like poles repelling property of these magnets hoping to get a floating platform. Still working on it.

Works as hoped

I needed to be able to easily swap pieces for a 3D-printed toy. These magnets were small enough to hide in the recesses of the main body and the swapable parts, and yet still strong enough to hold the pieces together.

Great Value

Bought these to hang curtains in a van. They don't go well when working through a layer of thick fabric, but they were so cheap and delivery was great that i'll just order some stronger ones. Brilliant little magnets though!

AMF Magnetics reply: Hi Ryan, thank you for your feedback! The pull force of a magnet will diminish when there's a gap (ie. a layer of thick fabric) – but you're quite right, you could try the application again with stronger magnets.
