Uses for our Rare Earth Ring Magnets:
Neodymium Rings play important roles in remote communities where access to modern utilities and amenities is limited and expensive. Solar power generating systems designed for use in remote locations use these magnets to simplify the unit's operation and reduce the levels of maintenance. Technicians are often a lot more than a phone call away and that's assuming you even have mobile phone reception.
Securing or stabilising solar panels with magnets to metal roofs or brackets makes them easily interchangeable or replaceable and easy to remove and send to a major regional centre for repair. Relocatable dwellings, tin sheds, containers or portable buildings can use magnets to adjust the position of panels as location or seasons change, achieving optimal exposure for battery storage and by avoiding the use of penetrative screws or bolts, these surfaces remain water-tight and weather-proof. In remote communities, power generation is crucial for efficiency and the ability to live and work in isolated regions for prolonged periods. Strong Ring magnets help to achieve these goals by providing practical and cost-effective solutions to the needs of those living or working in isolated areas.

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.
