Magnetic Product Description:

This rare earth disc has a diameter of 15mm and a height of 5mm. It has a pull force of 5.48kg. It is identified by the AMF magnet part number 20020A.

Uses for our rare earth disc magnets:

Magnets like these are ideally used for applications where magnetic strength is important but surface area is restricted. The reduced pole surfaces footprint is boosted in magnetic strength by the thickness of the magnet which reaches 1/3rd its diameter and pull force is further enhanced by the N42 Grade magnetic material it is made of. The dimensions of this magnet allow it to be recessed into wood or plastic to a depth of 5mm and secured with glue. They are commonly used in Metal separation and decontamination, water conditioning, metal detectors, tool and knife holders, wall stud and noggin locators, magnetic healing therapy, magnetic folder closures and cabinetry.

Neodymium Disc Magnet - 15mm x 5mm (20020A)

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.

fantastic magnets, experiment worked well

conducted an experiment with Y11 Physics students - force on a current carrying wire in a magnet field. Magnets worked well.

Door latch

Full size sliding glass door needed a magnetic latch that would hold. This magnet did the trick beautifully.

Powerful Little Suckers

Never used rare earth magnets before, but wow these are strong.

Prototype motor that will spin for 15 years

I'm working on a prototype motor that will spin for nearly 6 years unaided, not with the magnets I've bought here – with the magnets I will be buying later on which will have a talk at the shaft of about 200kg.
