Neodymium Disc Magnet - 10mm x 3mm | North Marked

Rated 5.0 out of 5
Based on 1 review
Product Code 20051
Pull Force* 1.7kg
Weight 2 gm
Style Rare Earth Disc marked magnet
Coating Nickel (NiCuNi)
Direction of Magnetisation Axially magnetised
Dimensions Height:3mm, Diameter:10mm

Magnetic Product Description:

This Rare Earth disc magnet has a diameter of 10mm and a height of 3mm. It has a magnetic flux reading of 3396 Gauss and a pull force of 1.96 kg. It is identified by the AMF magnet part number 20051.

Uses for our Rare Earth Disc Magnets:

This magnet has a handy mark identifying the north magnetic pole on the round, flat surface and has extra strength for its size due to its N42 Grade magnetism. Ideal where two magnets are configured in a north/south arrangement to attract and hold together. The mark also helps to determine the north or south poles on other unmarked magnets by repelling or attracting to the surface in question. Handy for magnetic binder or brochure closure systems and are also sewed into clothing, costumes and fabric enabling discreet fastening when arranged in the north to south alignment.Also used in electric DC motors, sensors, switches and monitoring devices.

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.
