Neodymium Disc Magnet - 6mm x 3mm | N38M

Magnetic Product Description:

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 807 grams. It is identified by the AMF magnet part number 93003.


Uses for our rare earth disc magnets:

Neodymium Discs have great versatility and can be used in so many different applications due to their strong pull force and adaptable shape. A great feature of this specific rare earth magnet is that it can tolerate a higher temperature than usual Neo magnets. The N38M grade can withstand temperatures of 100 degrees Celsius, as opposed to lower grades that will only manage temperatures of 80 degrees Celsius before they lose their magnetic integrity and decrease their pull force. This diversifies this small disc magnet considerably as they are now able to function in hotter temperatures with their high pull force. This unique magnet would be perfectly suited to use within motors and industrial environments.

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.

Perfect for "permanent" fridge pins

These magnets are fantastic, so small yet so powerful and CHEAP. They are very difficult to pull apart and are guaranteed to stick to pretty much anything. Perfect for attaching things to fridges or whiteboards if regular magnets don't quite cut it.

A firm grip

Thanks guys for supplying the ordered magnets. They are stronger than I anticipated which is fantastic. Delivery was quick. I will certainly be buying more magnets from you guys. Thanks
