Product Description:
The neodymium magnetic ring, also known as a rare earth ring magnet, has an outer diameter of 5mm, a height of 2mm and an inner diameter of 2mm. With grades ranging from N30 to N50, this N45 ring is a strong magnet ring with a strong magnetic force.
Neodymium magnetic material offers the highest magnetic strength compared with other permanent magnetic materials. They have a wide range of uses. Because this tiny ring-shaped magnet is very strong for its size and weight, it can be integrated into small products to utilise the magnetic properties. The magnets can activate switches and circuitry as they interact with electromagnetic fields.
Other uses include two of these small permanent magnets being used to create a magnetic bond between two surfaces. This would avoid the use of conventional attachment methods such as clips, pins or glue.
The rings can be used as magnetic folder closures for hobbyist scrapbooking or with commercial brochure manufacturers which are increasing in popularity. Jewellers and costume designers also find magnetic hold a practical and inexpensive option for their creations.
The ring shape of this magnet makes it easy to be attached to items using thread or wire. This is particularly handy and useful for those using them for crafting purposes.
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.
