This rare earth disc has a diameter of 20mm and a height of 1mm. It has a pull force of 1.1kg. It is identified by the AMF magnet part number 20018B.

Uses for our rare earth disc magnets:

The super thin profile makes this magnet easy to embed inside clothing, hems, jackets and sporting apparel in order to provide a discreet or invisible clasping or fitting system. These slim Rare Earth discs are also used for ferrous metal separation, metal detectors, tool and knife holders, wood and metal wall stud finders, magnetic health therapy, magic tricks, brochure and protective covering closures. The wide surface area creates adequate holding power for the attachment of brackets or equipment to metal surfaces. Epoxy Glue can also be used to attach the magnet to non-metallic surfaces.

Excellent product.

These are the right size to use in the bases of the figurines of my knitted nativity. They stood well on top of the upright freezer.

I would take a photo but, as it is after Xmas, they are already packed away.

Quality Magnets worth the Cost

We use these magnets in the activity called Geocaching. When you need a magnet, I've found these types are worth the cost of have a quality magnet to keep the geocache in place, out of sight. The magnet seems to outlast the container and when the container is tired I can reuse the magnet. It is the thinness of these magnets that make them perfect for geocaching.

I bought these for kids to make fridge magnets with fimo.. I broke one when they all jumped back together! Sent them to the kids anyway with strong apologies to the parents, but like the idea that it’s a togetherness project. They arrived safely but why w

Great! Want more

No FAQ available

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.
