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.

Small but mighty!

Three small magnets… but wowsers, they’re incredibly strong! Really impressed with them and can see that I’ll be buying more in the future.

Hi Janine,

Thank you so much for taking the time to share your experience and for this fantastic 5 star review!

We're thrilled to hear these 20mm x 1mm N38 neodymium disc magnets are living up to the "small but mighty" description! You've perfectly captured what makes these thin profile magnets so impressive - despite being just 1mm thick, they really do pack incredible magnetic strength that often surprises people with their holding power.

It's wonderful to know you're so pleased with their performance and that you're already planning future purchases. These versatile little discs are perfect for so many applications where you need strong magnetic force in a slim, compact form.

Thank you for choosing AMF Magnetics for your magnetic solution needs!

Hi Andrew,

What a fantastic review to receive! We're absolutely thrilled to hear you think the quality is excellent - that's exactly the kind of enthusiastic feedback that makes our day!

These 20mm x 1mm neodymium disc magnets really are impressive with their ultra-slim profile. At just 1mm thick, they provide that sleek, low-profile design while still delivering reliable N38 grade magnetic strength. The 20mm diameter gives you a great surface area for holding power, making them perfect for applications where you need strong magnetism without the bulk.

We're so pleased both our service and product quality met your expectations. There's nothing better than hearing everything exceeded what you were looking for!

Thank you for the amazing 5-star review and for choosing AMF Magnetics!

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.

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.
